Fall Brawl '98: War Games was the sixth Fall Brawl professional wrestling pay-per-view (PPV) event produced by World Championship Wrestling (WCW). It took place on September 13, 1998, from the Lawrence Joel Veterans Memorial Coliseum in Winston-Salem, North Carolina. As of 2014 the event is available on the WWE Network.

Nine matches were contested at the event. In the main event, Team WCW (Diamond Dallas Page, Roddy Piper and The Warrior) defeated nWo Hollywood (Bret Hart, Hollywood Hogan and Stevie Ray) and nWo Wolfpac (Kevin Nash, Lex Luger and Sting) in a WarGames match, with Page pinning Ray to win the match and earn a WCW World Heavyweight Championship opportunity at Halloween Havoc. In another prominent match, Perry Saturn defeated Raven in a Raven's Rules match to free The Flock from Raven's control.

The event garnered negative reviews from critics, with the matches being criticised for lacking substance and setting up angles instead, and is regarded as one of the worst PPVs in WCW history. However, the Raven's Rules bout received praise, and was singled out as the best match of the night by most critics.

The WarGames match was created when Dusty Rhodes was inspired by a viewing of Mad Max Beyond Thunderdome. It was originally used as a specialty match for the Four Horsemen. The first WarGames match took place at The Omni in Atlanta during the NWA's Great American Bash '87 tour, where it was known as War Games: The Match Beyond. It became a traditional Fall Brawl event from 1993 to 1998.

The event featured professional wrestling matches that involve different wrestlers from pre-existing scripted feuds and storylines. Professional wrestlers portray villains, heroes, or less distinguishable characters in the scripted events that build tension and culminate in a wrestling match or series of matches.

Prior to the match between Rick Steiner and Scott Steiner, WCW commissioner J. J. Dillon warned Scott that he would be permanently banned from WCW had he refused to wrestle against his brother in any way, even via no-show or forfeit. The match ended in a no-contest after Buff Bagwell pretended to re-injure his neck. As per a prematch stipulation, Saturn's victory freed The Flock from Raven's control; if Saturn had lost, he would have had to become Raven's servant. Chris Kanyon was also handcuffed to the ring. During the match, Kidman interfered on Saturn's behalf. In the WarGames Match Diamond Dallas Page pinned Stevie Ray after a Diamond Cutter. For the first time ever in a WarGames match, pinfalls were allowed. As a result of Page getting the pinfall victory; Page earned a shot at the WCW World Heavyweight Championship at Halloween Havoc.
