I have various Street Fighter games stretching across lots of platforms. I have 4 versions of Street Fighter Alpha 3 ( DC, PS1, PS2, PSP ), 3 versions of Street Fighter 2 ( Megadrive, SNES, PS2 ), 2 versions of every other Alpha game and a few others which I cant be bothered to remember. I have other cross-platform games which Ive gotten, but Street Fighter is the one series where I have almost every game. The Street Fighter series has 22 games, and I own probably around 35 titles, a result of cross-platforming.
