What it is
An arcade version of Super Street Fighter IV was released by Capcom in December 2010, titled Super Street Fighter IV: Arcade Edition. Arcade Edition added Yun, Yang, Evil Ryu and Oni to the roster, as well as changes to the existing characters.
Super Street Fighter IV takes place at the same time as SF4, several months after the events of Street Fighter II (thus is chronologically set between Street Fighter II and III). After M. Bison's survival following his encounter with Akuma, the S.I.N. corporation began another fighting tournament in order to draw out the most powerful fighters on Earth to complete the BLECE project. Each character has their own reasons for entering this tournament, but S.I.N.'s real desire is to lure Ryu to them in order to analyze the Satsui no Hadō, believed to be the last piece of data needed to complete BLECE.
