Final Fight Guy (SNES)

Final Fight Guy is a revised edition of the SNES Final Fight that replaces Cody with the formerly-missing-in-action Guy, while making a bunch of other less-obvious changes that were not as blatantly advertised. Because of this, Capcom did not feel confident enough to release it in the US (as they were not used to rehashing their own games back then) until two years after the Japanese version... as a Blockbuster store exclusive. Needless to say, the US version has become one of the more sought-after cartridges among SNES collectors.
