Stars! is a turn-based strategy, science fiction 4X video game (eXplore, eXpand, eXploit, eXterminate), originally developed by Jeff Johnson and Jeff McBride with help from Jeffrey Krauss ("the Jeffs") for personal use, initially released as shareware for Microsoft Windows in 1995.[2] A retail version was later produced for, and published by Empire Interactive, with developer Jason Gaston added to the team for quality assurance testing, although the shareware version continued.
The game focuses on players developing their empires, engaging in diplomacy, and conquering the galaxy. It begins with race design, and features 2D graphics and a grid-based battle system. The game is well-adapted to Play-By-Email and also supports AI opponents, blitz games, and duels. Stars! is compatible with most Windows versions and can run on Linux systems through Wine. While it received generally positive reviews for its depth and multiplayer focus, its complexity and single-player appeal were criticized. A sequel, Stars: Supernova Genesis, was abandoned due to lack of publisher interest.
Gameplay
[edit]Starting with a small fleet of ships and one or two planets, players develop their empires, meet other races and conquer the galaxy. Stars! games begin with race design, choosing one of 10 primary racial traits, a selection of lesser racial traits, habitability, growth, economic, and technology settings.[3] The graphics are entirely 2D, and consist of the main map view and static pictures of planets, ship hulls and components. Battles consist of moving static icons around a grid. Because of the high level of micromanagement and diplomacy requirements, many games take place over months between players spread across the galaxy.
Players initially send scouts out to scan for suitable planets which later may be colonized and developed, enlarging the player's empire and providing additional resources. As a player's empire expands the player must balance the management of the population, minerals, research, and ship/infrastructure constructions. When other players' races are encountered, a variety of diplomacy options allow for alliances, trading mineral resources or technology, large-scale wars, and even the destruction of other races. If the random events game option is enabled, players will have to contend with (or take advantage of) the Mystery Trader, comet strikes, wormholes, and environmental changes.
Modes of play
[edit]The game is well adapted to the Play-By-Email (PBEM) style of multiplayer gaming. One player takes on duties as host, and the other players will send their instructions (turn files) by email to the host. The host then uses their copy of the game to generate the next turn, including the players' instructions and emails back the new game state file.
An alternative to play-by-email is to use an online system such as the Stars! AutoHost. This system automates most of the hosting duties and can handle a large number of games simultaneously.
Many games are run at a rate of one turn per calendar day, giving plenty of time for strategic thinking. In large games, this can be necessary, with turn generation dropping to only three times per week in cases due to the complexity of the game and the level of micro-management required to effectively control a large empire competitively. To foster a better understanding of the game, Mare Crisium paid members of the player community (Kearns, Clifford, Steeves) to write and edit an in-depth Strategy Guide in 1998.[4]
There is also an artificial intelligence (AI) that can take part in the game. The player can opt to play against AIs only (up to 15 of them), and this is the way that new players typically get to learn the game mechanics before launching into multi-player games. A tutorial helps with getting started.
Another style of play is referred to as a Blitz game. In these games, turns are played every 15 minutes or so, and all players must be at their computers at the same time. Blitz games are generally more tactical and less political in nature, due to the time constraints involved.
The duel games are similar to regular turn-a-day ones, but are between two players only. Again, with only two players involved there is no political side to these games.
Compatibility
[edit]Stars! can be run on most versions of Windows from Windows 3.1 up. It can even be run on Linux systems through the Wine system. However, under Wine, version 2.70 crashes during combat if combat sounds are enabled. Stars! does not run directly on the 64-bit version of Windows XP, Windows Vista or Windows 7, which cannot run 16-bit software. However, it can be played on a virtual machine-like Virtual Windows XP on Windows 7,[5] or in VirtualPC on earlier 32-bit versions of windows. Another alternative is VirtualBox. It also runs quite well using Windows 3.11 installed in DOSBOX.[6] Preview version (32bit) of Windows 10 plays version 2.60i. On 64-bit Windows 10, version 2.70i runs well on Wine for Windows version otvdm-v0.7.0.
Development
[edit]The game was originally developed in 1995, with version 2.0 released early in 1996. Later that year the newsgroup rec.games.computer.stars became active, facilitating public discussion of tactics and allowing players to find new games.
The game was originally developed by Jeff Johnson and Jeff McBride with help from Jeffrey Krauss ("the Jeffs") for personal use, initially released as shareware for Microsoft Windows in 1995.[2] A retail version was later produced for, and published by Empire Interactive, with developer Jason Gaston added to the team for quality assurance testing, although the shareware version continued.
By the end of 1996 shareware version 2.60 had been released, and the game has remained essentially unchanged ever since, although there have been numerous updates. Version 2.70 is the retail version which has battle sounds and allows research past Level 10 (the shareware version is restricted). The latest file date on the retail version CDROM is January 8, 1997; it sold for $41 before tax at Media Play in the southeastern U.S. in February 1997. The manual was 15mm thick (over half an inch), but the game only needed 2 MB of installation space. The most recent patch version, 2.60j RC4 (release candidate 4) was released in December 2000. Versions 2.60 and 2.70 are compatible as long as the minor version letter is the same (e.g.: 2.60i can play with 2.70i players). Over the years a number of third-party developers have provided tools and utilities to help players manage their empires.
Reception
[edit]Reception
| Publication | Score |
|---|---|
| Computer Game Review | 80/93/89[7] |
Stars! has received some generally positive reviews. PC Gamer UK's reviewer Andy Butcher gave the game a rating of 79% in its February 1997 issue, commending it with the following comment: "What makes it stand out from the many games based on a similar idea are its depth, and that it's been designed right from the start with multi-player gaming in mind". Pitfalls he mentions include that the large number of options available can make the game confusing, and that the game is likely to be less appealing to single players.[8]
GameSpot's reviewer T. Liam McDonald rated the game 7.3 "Good", applauding "a solid Windows interface, plain graphics, a wide range of custom options, deep strategic content, and compulsive playability" and stating that the game outdoes the similar game Spaceward Ho! 4.0.[9] In Computer Game Review, Tasos Kaiafas wrote, "Stars! may not be brilliant, but it is fun and well designed."[7]
Sequels
[edit]The huge popularity of the original Stars! game convinced the developers that there would be a market for a sequel. The developers of Stars! formed a company called Mare Crisium Studios and began development of Stars: Supernova Genesis. This was intended to be a much more advanced game, with significantly better graphics, and also to remove some of the irritations of the original, such as the high level of micro-management.[10]
However, there was little interest from games publishers, who by that time had become focused exclusively on the video game console and high-end 3D games markets, and so the project was eventually abandoned. Rights to the in-game graphics remained with Empire, until they were acquired by Zoo Games.[11]

Overview
Introduction
Stars! is a turn-based 4X strategy video game developed by Jeff Johnson and Jeff McBride, with additional programming by Jeffrey Krauss.[5][6] Initially released as shareware on November 20, 1995, for Windows 3.1, the game was later published in retail form as version 2.70 by Empire Interactive in 1996.[1][2] In Stars!, players assume control of customizable alien races within a procedurally generated galaxy, managing empires through exploration, expansion, resource exploitation, and conflict with other races.[1] The core premise revolves around achieving dominance via traditional 4X mechanics—explore, expand, exploit, exterminate—or alternative victory paths, supporting up to 16 players (including human and AI opponents) in single-player or multiplayer modes via play-by-email.[7] The game features a 2D top-down interface suited to its Windows 3.1 origins, emphasizing strategic depth in fleet management, technology research, and interstellar diplomacy without relying on real-time action.[1] This design allowed for complex simulations of galactic conquest on early personal computers, distinguishing it as a seminal shareware title in the genre.[8]Core Concept and Genre
Stars! is a turn-based 4X strategy game, encompassing the core pillars of eXplore, eXpand, eXploit, and eXterminate, where players engage in long-term planning to build and manage interstellar empires across vast galaxies.[1] Unlike real-time action-oriented titles, it prioritizes deliberate decision-making in resource allocation, technological advancement, and territorial control, allowing for asynchronous multiplayer via play-by-email or single-player against AI opponents.[9] This structure fosters strategic depth through turn-based progression, enabling players to simulate years of galactic history in each session.[3] A hallmark of Stars! is its highly customizable race creation system, where players design species using genetic traits selected via an advantage-point system, influencing aspects like population growth, technology costs, and special abilities—such as Hyper-Expansion for rapid colonization or Super-Stealth for covert operations.[9] Ship travel employs a unique packet-based mechanic, where vessels consume fuel to achieve warp speeds up to 10, with travel distance calculated as the square of the warp speed; mineral packets, used for transport and construction, decay over time and can double as weapons or terraforming tools when launched via mass drivers.[9] Victory conditions extend beyond mere conquest to include technological supremacy, population dominance, achieving score thresholds (ranging from 1,000 to 20,000 points), or surviving a predefined number of turns (30 to 900 years), with options for custom player-defined goals.[9] Set in a procedurally generated sci-fi universe featuring dynamic star systems, diverse planets, and anomalies like wormholes, Stars! eschews a fixed storyline in favor of emergent narratives driven by player choices and interactions.[9] Compared to contemporaries like the 1993 Master of Orion, it offers deeper race customization and spatial strategy elements, though with simpler 2D graphics and a more utilitarian interface.[10]Gameplay
Race and Empire Management
In Stars!, players begin by designing their race using the Custom Race Wizard, a point-based system that allows customization of primary and secondary traits to balance strengths and weaknesses. Trait costs vary depending on the chosen primary racial trait, influencing the overall balance. The system starts with a base allocation of advantage points, which are spent on traits such as Hyper-Expansion, which doubles the maximum population growth rate but halves the maximum population capacity to 500,000 on optimal planets, or War Monger for combat bonuses including unique hulls and beam weapons; unspent points provide starting bonuses like additional mines or factories on the homeworld.[9] Disadvantages, such as Generalized Research, which allocates 50% of research output to the current field and distributes the remainder evenly across the other fields, can be selected to gain extra points and offset costs of powerful advantages.[11] This design process ensures strategic trade-offs, with trait costs varying— for example, Claim Adjuster (automatic terraforming upon colonization) costs 53 points, while Total Terraforming (up to 30% environmental improvement) costs 140 points—tailoring the race to playstyles focused on expansion, stealth, or warfare.[11][9] Empire building centers on colonizing planets and managing population growth to expand territorial control and production capacity. Colonization requires transporting colonists via colony ships or freighters, with successful establishment depending on habitability factors like gravity, temperature, and radiation, which determine the planet's maximum population, typically up to 1,000,000 for standard races (500,000 for Hyper-Expansion races or 1,200,000 for Jack of All Trades races).[9] Population grows at a base rate of 1-20% per turn, influenced by habitability (below 0% causes death after one year) and traits like Hyper-Expansion, which doubles the rate to enable rapid settlement of new worlds discovered through exploration.[9] Once established, colonies support infrastructure such as mines for mineral extraction, factories (each costing 4 kT of germanium) that double resource output from the population, and defenses that mitigate bombing or invasion damage; overcrowding above 100% habitability reduces efficiency, while terraforming technologies or traits like Claim Adjuster improve conditions over time.[9] Starbases serve as key hubs for ship construction and further expansion, particularly for Alternate Reality races that rely on them instead of planetary buildings.[9] The technology tree comprises over 150 advancements across six categories—Energy, Weapons, Propulsion, Construction, Electronics, and Biotechnology—each progressing through 27 levels (0-26), with prerequisites ensuring sequential development.[9] Research is allocated directly from planetary resources via the Technology Browser, where players assign output to specific fields; costs escalate with higher levels, but achieving levels beyond prerequisites reduces production costs for ships and components by 5% per excess level, up to a 75% discount.[9] Racial traits modify efficiency, such as Bleeding Edge Technology for faster progress at higher difficulties or Generalized Research, which allocates 50% to the selected field and distributes the rest across others for balanced but slower advancement; for instance, Propulsion tech enables faster engines, while Biotechnology improves population growth modifiers.[11][9] This system emphasizes strategic allocation, as total research capacity scales with empire population and factories. Economic simulation revolves around resource production, conversion, and distribution to sustain growth and construction. Populations and factories generate "resources" as work units for research, building, and maintenance, while mines extract three minerals—Ironium (basic construction), Boranium (advanced components), and Germanium (high-tech items)—essential for shipbuilding and infrastructure.[9] Conversion mechanics include Mineral Alchemy, which recycles 25 resources into 1 kT of any mineral, and factories that amplify output; supply and demand fluctuate based on empire needs, with shortages halting production until imports arrive.[9] Trade routes facilitate logistics using freighters for direct transport, mass drivers to fling mineral packets between planets, or stargates for fuel-efficient ship movement, often automated via fleet orders; diplomatic agreements can exchange minerals, fuel (anti-matter), or even technologies to stabilize prices and access rare resources.[9] Traits like Advanced Remote Mining enhance off-world extraction, while Ultimate Recycling reduces waste, creating interdependent chains where basic Ironium feeds into complex assemblies limited by scarcer Germanium.[11]| Resource Type | Primary Use | Production Method | Example Trait Impact |
|---|---|---|---|
| Resources (Work Units) | Research, Building, Maintenance | Generated by population and doubled by factories | Jack of all Trades increases max population for higher output |
| Ironium | Basic Ship/Structure Construction | Mined on planets; alchemized from resources | Advanced Remote Mining boosts remote yields |
| Boranium | Engine/Weapon Components | Mined; transported via routes | Mineral Alchemy converts excess resources |
| Germanium | Advanced Tech/Starbases | Scarce mineral; key for factories | Ultimate Recycling minimizes losses |
| Anti-Matter (Fuel) | Ship Propulsion | Produced via Energy tech; traded diplomatically | Improved Fuel Efficiency reduces consumption |
Exploration and Resource Handling
In Stars!, exploration begins with the deployment of scout ships designed to map the procedurally generated galaxy and identify viable planets for colonization. Players customize the galaxy's parameters, including size (ranging from small setups to expansive maps supporting up to thousands of stars), density, and starting distances between empires, creating varied terrains such as star clusters and open voids.[9] Scouts, typically built on lightweight hulls like the Scout or Super Scout, are equipped with scanners to detect stars, planets, and fleet movements from afar; ship-based scanners calculate their effective range as the fourth root of the sum of each scanner's power raised to the fourth power, allowing for example a combination of two 100 light-year scanners and one 60 light-year scanner to achieve approximately 120 light-years of detection.[9] Nebula clouds obscure sensor readings within their boundaries, forcing players to rely on closer-range probes or direct fleet approaches to reveal hidden systems.[9] Ship design plays a central role in effective exploration, utilizing a modular system where players assemble vessels via the Ship Designer interface by selecting hulls and slotting in components such as engines, scanners, and armor. Hulls determine base mass, speed potential, and special abilities—for instance, the Rogue hull enables super-stealth cloaking for undetected scouting—while engines dictate warp capabilities, with standard engines requiring fuel and ramscoop variants harvesting it en route up to their maximum speed.[9] Weapons like beams or torpedoes can be added to scouts for defense against random encounters, though exploration-focused designs prioritize speed and sensors over firepower to minimize fuel costs and maximize range.[9] Once designed, up to 16 unique ship blueprints can be saved and produced at shipyards or starbases, with starbases offering 50% cheaper components to facilitate rapid fleet expansion for galaxy-wide surveys.[9] Fleets of these ships travel as "packets"—coordinated groups moving together at uniform warp speeds determined by the slowest vessel and overall mass, with arrival times calculated based on distance, warp factor (up to a maximum of 10, though 9 is safer to avoid structural damage), and technological efficiencies. Warp 1 travel is fuel-free, but higher speeds consume fuel proportional to mass, efficiency, and distance via the formula units per light-year.[9] Overthrusters or jets can boost packet movement by up to 2 squares per turn in tactical scenarios, while wormholes provide shortcuts, connecting distant stars with stability levels from rock-solid (lasting over 30 years) to very unstable (about 5 years), often cloaked until scanned and traversable without fuel cost.[9] Resource acquisition commences upon a packet reaching a star system, where orbiting scouts or survey ships use penetrating scanners—such as bat scanners for surface details or planet-penetrating radar for subsurface minerals—to assess planetary habitability, including gravity, temperature, radiation, and concentrations of key minerals like ironium, boranium, and germanium.[9] Surveys reveal mineral estimates accurate to within ±20% for neutral worlds, enabling players to prioritize colonizable planets with high yields; mines can then be established to extract 25 kilotons per year per mine, though concentrations deplete over time at a rate of 12,500 tons per mine-year.[9] For remote exploitation, mass drivers fling mineral packets at speeds from warp 5 up to the driver's rating plus 3, with faster packets decaying 10-50% annually if overdriven, and races with Packet Physics traits halving decay while using packets for scanning or even as improvised weapons.[9] Establishing outposts involves transporting colonists and supplies via freighter packets to surveyed worlds, where Mini-Colony ships (for races with Hyper-Expansion traits) can seed a planet with 10 kilotons of cargo in one drop, rapidly building populations and factories.[12] Transports, such as Super Freighters holding up to 3,000 kilotons, form supply lines by waypoint tasks for automated loading and unloading, ensuring minerals flow back to core worlds; stargates built on planets further streamline this by enabling fuel-free interstellar jumps for compatible fleets.[9] Starbases on outposts enhance local production and repair rates (10% annually, or 15% with Inner Strength traits), serving as hubs for further exploration fleets.[9] These discovered resources integrate into the broader empire economy to fuel sustained growth, as detailed in race management sections.[9] Exploration encounters random events that add depth to discovery, such as derelict ships offering salvage with a 50% chance of technological advancement, ancient artifacts catalyzing research breakthroughs, or mystery traders proposing tech exchanges.[9] Pirates or transdimensional beings may appear as hostile anomalies, requiring defensive ship designs, while environmental hazards like radiation storms can disrupt surveys but occasionally yield bonuses.[9] These mechanics emphasize strategic planning, as early scouting packets lay the foundation for resource networks that determine long-term galactic dominance.[9]Combat and Diplomacy Systems
The combat system in Stars! employs turn-based tactical battles on a grid, where fleets engage in up to 16 rounds of movement and firing, determined by ship initiative and battle plans.[9] Initiative is calculated from hull base values (0-18), augmented by battle computers (1-3 points) and racial modifiers, dictating the order in which units act.[9] Fleets maneuver 1-2 squares per round, influenced by engine speed, ship weight, overthrusters (adding 0.5 squares), and maneuvering jets (adding 0.25 squares), with disengagement possible after 7 squares of separation.[9] Weapons operate at varying ranges, such as beam weapons at 1-3 squares (with damage decaying 10% per additional square) and torpedoes at 4-6 squares, while starbases extend beam range by 1 square.[9] Ship statistics encompass hull mass, engines (up to Warp 10), shields that absorb initial damage and regenerate if equipped with the appropriate trait, and armor that withstands overflow damage (torpedoes affecting both).[9] Special abilities include cloaking devices, which reduce enemy scanner effectiveness up to 98% but can be countered by tachyon detectors (diminishing cloak by up to 95% based on quantity).[9] Capacitors enhance beam damage by 10-20% (capped at 250%), and repairs occur at 1-20% annually depending on facilities like owned planets with space docks.[9] Minefields serve as environmental hazards in space combat, forming circular grids that decay 1-50% yearly and can be swept by beam weapons, while energy dampeners slow all ships by 1 square per round.[9] Ground invasions resolve planetary control through troop deployments from freighters, converting colonists into combatants via transport orders; success depends on numerical superiority, with planetary defenses operating at 75% efficacy and requiring prior starbase destruction.[9] Orbital bombardments provide an alternative, utilizing bombers for infinite bomb drops or mineral packets (e.g., Warp 13 packets inflicting 1056 damage and killing 264,000 colonists), again necessitating the elimination of defending starbases.[9] Diplomacy facilitates interstellar relations through player designations of enemies, friends, or neutrals, accessed via the Player Relations dialog, which influences automated actions like terraforming (positive for friends, negative for enemies).[9] Treaties encompass trade in fuel, minerals, technology, or ships; non-aggression pacts; and alliances that enable shared benefits such as starbase refueling and stargate access.[9] Espionage manifests through scanning to reveal opponent fleet compositions and technologies, with stealth scanners enabling cargo piracy and super-stealth racial traits allowing automated theft via specialized devices like pickpocket scanners.[9] AI opponents adhere to predefined strategies, including expansionist or isolationist approaches that shape their expansion and interaction patterns, while the housekeeper AI manages idle players' assets without advanced decision-making.[9] Player-AI interactions occur via the messages pane for negotiations and reports, supporting cooperative elements like joint mining through fleet transfers.[9] Special racial abilities, such as claim adjuster traits, permit orbital terraforming of others' planets using adjuster devices, enhancing diplomatic leverage in multi-player scenarios.[9]Game Modes
Single-Player Campaigns
Single-player campaigns in Stars! emphasize strategic depth through competition against artificial intelligence opponents in procedurally generated galaxies, allowing players to design custom races and configure game parameters for varied solo experiences. Campaign setup begins with the New Game dialog, where players select galaxy size ranging from tiny to huge on a scale of 0-4, density from 0-3, starting distances between races from 0-3, and the total number of participants up to 16, including the player and AI foes.[9] Victory conditions are customizable, such as achieving a target score, dominating through conquest, or enabling multiple winners via alliances, with scenarios like "King of the Hill" focusing on balanced starting positions and territorial control to simulate competitive escalation.[9] These parameters enable tailored challenges, where smaller galaxies favor rapid expansion strategies, while larger ones demand extensive fleet management and long-term planning.[12] The game's 10 preset AI races provide diverse opposition, each with unique traits and strategies that adapt to the player's approach, ranging from aggressive expansion to stealthy resource denial. Examples include the Hyper-Expansion race, which prioritizes rapid colonization and population growth; the War Monger, focused on early military buildup and direct assaults; the Super-Stealth, employing cloaking technologies for espionage and surprise attacks; and the Packet Physics, utilizing mineral packets as improvised scanners and weapons.[12] Other notable races are the Claim Adjusters, who automate planetary terraforming for efficient resource extraction, and the Insectoids, emphasizing swarm-based warfare tactics.[9] Difficulty levels—Easy, Medium, Hard, and Expert—scale AI competence and advantages, with Expert mode granting additional "advantage points" for enhanced starting resources or traits, creating a learning curve from novice-friendly simulations to expert-level strategic duels where AI starting positions are randomized to prevent predictability.[9] This setup ensures AI opponents evolve dynamically, responding to player expansions with tailored countermeasures like blockades or tech theft. Progression in single-player campaigns unfolds through turn-based advancement, with each annual turn processed via the F9 key, allowing players to issue orders for exploration, colonization, research, and combat without real-time pressures.[9] Auto-save features, configurable in thestars.ini file, create backups up to 999 turns, complemented by manual saves to preserve long sessions that often span hundreds of turns due to the game's emphasis on deliberate planning over reflexive actions.[9] In AI encounters, core combat mechanics resolve fleet battles on a grid-based system, rewarding optimized ship designs and tactics honed through iterative play.[12] These elements culminate in extended campaigns that test resource allocation and diplomatic feints against AI races, though the absence of real-time elements limits appeal for players seeking fast-paced action, instead highlighting meticulous empire-building.[9]
