I got Mega Man 9, I love classic games and thought it would be fun. It's a bit too difficult IMO. Though I am characteristically bad at Mega Man games.
Cool idea though, very original. I'd like to see other game franchises do this. (Sonic and Mario to be specific)
Considering Sonic was at his peak in the early 90's - YES. They really do need to do this for the blue chap!
