Clone Wars Adventures was an online virtual world based on the animated television series Star Wars: The Clone Wars. Players could create and customize in-world avatars and participate in a variety of Clone Wars-themed mini-games and activities, earning Republic credits to purchase new weapons, outfits, ships, and furniture. Clone Wars Adventures was free to download and play, but only those with a paid membership got access to a majority of the game's features. Additionally, many outfits and premium items could only be purchased with Station Cash, a form of in game currency that players needed to purchase with real money instead of in-game credits. This massively multiplayer online game follows a similar business model to Free Realms. However, unlike Free Realms, the game was released at retail, though the game is free-to-play.

Clone Wars Adventures reached one of its milestones after 10 million players registered for the game. The first ten million players who joined were given a free Golden Death Watch set and a huge presentation of game statistics from Sony Online Entertainment, or SOE (now Daybreak Game Company), since the game's launch. On January 24, 2014, SOE announced that the game would be shut down on March 31, 2014.

The in-game world of Clone Wars Adventures was set in the Jedi Temple on Coruscant set between the Star Wars films Attack of the Clones and Revenge of the Sith. Here, players could interact with popular Clone Wars characters like Anakin Skywalker, Mace Windu, Yoda, and Obi-Wan Kenobi and play more than 20 different mini-games, including Lightsaber Duel, Republic Defender, a tower defense game, and Speeder Bike Racing. Other mini-games were campaign-based on Seasons 3, 4, and 5 from The Clone Wars. Players can challenge each other in multi-player games to win Credits. Even though the game was based on the Jedi Temple, players could travel to different planets like Ryloth, Umbara, and Carlac when going to the hangar bay. Players could also interact with other players using the world chat, which allowed communication and chatting to a certain distance, or private chat, which allowed players to run a conversation with only one other person. Players were also given a buddy list to add and chat with friends and an ignore list to block all communications and requests from that particular player. Additionally, Members could even create player guilds (squads) to allow maximum interaction with friends and access to a private chat room. All players were given options to play games, build on their own lots, participate in events, and much more. The environment of the game is constantly changing, with weekly updates adding content to the game for players to experience for themselves.

Clone Wars Adventures offered a huge selection of mini-games including strategy, action, puzzle, racing, and combat games. Mini-games were initially any player's main source of income — Republic Credits. However mini-games also offered challenges and goals for players. There were 30+ mini-games for players to play. Non-members were given partial access to a minority of the games, while paying Members were rewarded with total access and the full experience to each mission. Most mini-games had their own trophies that came along with completing a challenging feat in that certain mini-game. Select mini-games had their own title that were associated with it like Jedi General for Republic Defender or Jedi Ace for Starfighter. Another game is Lightsaber Duel. Titles for that included: Blademaster, Duelist, and Sentinel.

Players could engage in battles with droids, Umbarans, Death Watch troopers, and infamous characters like Darth Maul in combat zones. The game offered two combat zones, Umbara and Carlac which contained active quests, missions. Players could explore these worlds by foot or vehicle, and face dangerous enemies. Typically, all AI enemies dropped two Republic Credits that players could use to purchase a wide variety of items, and leftover scrap items. Using the player combat system, a diverse system of fighting for both AIs and players alike, both members and non-members could unleash powerful attacks upon their opponents who usually dropped a special piece of material used to craft various items or complete collections. Players were given access to abilities that depended on the current weapon the player was using, power-ups with companions, and field equipment to aid them in combat.

Players could purchase droid companions like R2-D2 or TO-DO to follow them around in game. There were also special attachments that allow pets to do new things, like a boombox to make other players dance, or mounted guns to fire lasers when clicked on. Players could also unlock more droids like C-3PO by entering special game codes on the Clone Wars Adventures website home page. Other companions included adopted creatures such as Jawas. There were several Creature Pets available such as the Convor, a bird-like creature, with helmet attachments available for purchase. Other creatures included an Anooba, Kowakian monkey-lizard, a brown rancor, and a red rancor, which could only be obtained by receiving the pet in a special crate and purchasing an SC Code to open it. In addition to the entertainment of owning a companion, players were also given special abilities associated with their current pet. These power-ups provided boosts like speed and extra-damage while both on and off the battlefield.

Battle Classes were introduced to players on the update of September 28, 2012. The system allows a more achievable set of goals and rewards upon defeating enemies in combat zones. Players were given four primary battle classes, Jedi, Trooper, Sith, and Mercenary to rank up in and obtain exclusive rewards. The Trooper class was both set as a default for all players and free, while sinister classes, Sith and Mercenary, required a Station Cash purchase of 750 SC to experience. Unlike the other battle classes, Jedi was only accessible through a paid membership without any additional purchase. Additionally, paying members were given a 50% discount on the Sith and Mercenary classes alike. All battle classes required experience points to allow players to rank up in. Experience points were dropped by defeated enemies in combat zones and mini-games. Ranks gradually became more difficult as the player progressed through that particular class. Along with ranking up, players were given a whole new set of titles corresponding to rank as well as several pieces of wearable gear. Specialty Classes, alongside battle classes, differed in several ways, including the fact that they did not require combat zones to progress in. Specialty classes were passive player classes used within certain mini-games and were ranked up via certain activities. For example, the Scoundrel class incorporated Card Assault, a card based mini-game, with this specialty class. Upon the completion of campaign missions, the player rose through the ranks and was rewarded a special deck of cards.

Clone Wars Adventures used two forms of currency: Standard "Republic Credits" and "Station Cash". Republic Credits allowed players to purchase items or companions throughout the game. These were obtained through various activities ingame, whereas "Station Cash" was a premium currency that could be obtained through microtransactions, allowing players to purchase access to otherwise exclusive in-game items and challenges. It was free to download and play, but free players had restricted access to mini-games, equipment, furniture, and game areas. For a monthly subscription fee, members had full access to game content, excluding any premium items that must be purchased separately with station cash, such as original costumes or exclusive actions and housing items. Members were given access to VIP areas, more Mini-Games, the ability to wield dual-lightsabers, member-only items, the exclusive Jedi battle class, and a special deluxe house. Members were also allowed access to more mini-games, furniture, and extra game content.
