I think there were a total of 6 Street Fighter 2 releases on Sega Genesis and Super Nintendo. Each only slightly different than any other. It was ridiculous.

I picked up one Street Fighter 3 game on Dreamcast, there were two. I think I have Double Impact. Capcom are the king's of milking a franchise.

I think Midway would have done it with Rampage had there been enough fan support.

Here is a vid for King of the Monsters. It was released on Neo Geo, SNES and Genesis. Also on compilations, of course.
