The cover of SFA has made it to quite a few "Worst game cover ever"-lists, in both printed and digital media, and it's easy to see why... What IS wrong with Ryu's arms and why is Chun Li so husky? Who approved that cover?
This was one of the first 2D games to be released for the PlayStation.
This game was inspired by the Street Fighter animated movie (not Van Damme's). Specifically, the movie's flashback sequences, which explain Ryu's slight hair color change, and Ken's ponytail. However the coolest movie tie-in the game has is the ability to play a cooperative match with a friend as Ryu and Ken versus M. Bison (with all three characters on screen! not like Capcom's "vs" series) mimicking the movie's final battle.
The character Dan (who made his first appearance in this game) was made as a sarcastic response to Capcom's main competitor on arcade games SNK, who have for years been stealing and cloning Capcom's ideas. As such Dan sports many details reminescent of some SNK characters (his storyline, the ponytail, etc.) and is quite literally a bad clone of Ryu and Ken who has lots of taunting moves but no real power.
