I didn't realise sonic CD on PSN was made from the ground up. Its even got tails added in. I think i might grab it, its on sale in game.
Dunno if you guys have played it before but the premise is pretty damn crazy and makes it sound like one helluva crazy platformer, you time travel midlevel which alters the level or something. I played it when i was little and had no clue what the hell I was doing so I stopped playing. Think I might give it a shot now though,
