A 3d tv series base on 2001 Nintendo gamecube Melee includes all playable characters from the first game, and also adds characters from franchises such as Fire Emblem, of which no games had been released outside Japan at the time. Melee's gameplay system offers an unorthodox approach to the fighting game genre, with a counter that measures damage with increasing percentages, representing the knockback the character will experience, rather than a depleting health bar seen in most fighting games. It builds on the first game by adding new gameplay features and playable characters. Following the popularity of its multiplayer gameplay, Melee has been featured in many competitive gaming tournaments, and is one of the most popular competitive fighting games.
