Marvel Super Heroes vs. Street Fighter is the fourth Marvel Comics-licensed fighting game produced by Capcom (see Marvel vs. Capcom series). It is a sequel to X-Men vs. Street Fighter which replaces most of the X-Men characters with characters from Marvel Super Heroes. In an attempt to balance the previous games' problems, the game engine was altered, although it remained aesthetically the same. The game was released for the arcade in 1997, Sega Saturn in 1998 and Sony PlayStation in 1999. [source:wikipedia]
