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. 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.
