Capcom's Street Fighter II did not just popularize fighting games; it essentially created the competitive gaming scene. Its roster of eight (later twelve) characters each played completely differently, creating a depth of matchup knowledge that kept players feeding quarters into arcade cabinets for years. The special move inputs (quarter-circle forward for a fireball, forward-down-diagonal for a dragon punch) became the universal language of fighting games. It sparked arcade rivalries, tournament scenes, and a level of competitive intensity that would not be matched until the esports era decades later.
