I liked the graphics in Matrimelee and I played the single player. No one ever played it on Supercade. I'd like to try that one out, it might be a little broken though.
Other then RB2 I'm most looking forward to playing Warzard. I think the gameplay is pretty tight, but it'll be interesting to play a fighter where there's only 4 characters. Let's see if tiers still apply to that one. Haha.
