Based on the CPS-3 hardware, which allowed a new level of visual fidelity, the Street Fighter III series continued to evolve the Street Fighter formula with the addition of new mechanics: the ability to parry attacks, leap attacks, as well as Super Arts, selectable special moves that use a power gauge. In addition to adding a variety of new characters to the Street Fighter III roster (because it wouldn't be a new Capcom fighting game without them) and new stages and endings tied to the returning characters, and continuing the EX special moves from 2nd Impact, 3rd Strike adds the Grade Judge system, which awards special bonuses based on how well you performed across several metrics (in case your friends and opponents trash talking you wasn't enough).
