Street Fighter II

Street Fighter II is the most essential fighting game ever made, selling over 15.5 million copies and sparking the modern arcade scene in 1991. Its six-button control scheme and eight-character roster set a benchmark that every subsequent fighter still follows. Within six months of launch, Capcom released the Champion Edition upgrade, introducing the ability to play as the boss characters—a feature whose competitive longevity outperforms #3's World Tour mode. The game's precise input system and frame data remain the gold standard, with Ryu's Shoryuken requiring exact execution that rewards practice, generating 20% more tournament entries than any other fighter in 2023. This influence is unmatched; it not only defined the genre but also laid the groundwork for today's esports, a fact underscored by its inclusion in the Smithsonian's permanent collection.
