So why are none of you talking about it? It came out two weeks ago on the XBLA and last week on the PSN. I've been playing it since Thursday and loving it. There are a lot more levels and modes than in the first Championship Edition, and a bunch of different skins and sprite styles that you can apply to any level. It's definitely a game based on speed and setting high scores, rather than simply clearing levels.
Nobody on my PSN list is playing this game because clearly they all suck.
