Capcom has released Street Fighter x Megaman, a PC exclusive title that pits Megaman in a cross-over Street Fighter world. If you play arcade fighters, it's similar to Street x Tekken, where the characters are taken from one and put into the grapgics/style of the other. The game plays like an old-school Megaman game, but with stages devoted to Street Fighter characters. And it's FREE.
