Yeah, I have. And I was let down. The retro graphics are a stupid idea. It's not the graphics that made six and seven suck. Eight had non retro art, and it was awesome. The stage music was bland, it wasn't bad (like MM5), but it wasn't any good either, it was just sort of there. The difficulty was too high. I don't mind a challenge, in fact, it wouldn't be Mega Man without one. But I don't like when a game is difficult, not due to excellent design, but by intentionally removing things that would aid the player. They took out smurfing slides. This game would have Mega Man X's difficulty level (which I think is the shining example of optimal difficulty)if you could slide and use charge shots. Also, MM9 is host to the dumbest set of robot masters ever. I mean seriously. Concrete man?
