It is a full-priced 2D platformer, which rubs some people the wrong way. However, and I can't stress this enough, I'm not going to be surprised if Rayman Origins ends up being my favorite game of 2011, based on what I've played of it so far. Fan of classic Rayman or not, you owe it to yourself to try the demo.
It's pretty much happiness incarnate. Conrad will have the review up before the game hits store shelves. It's not too late to get this one on your radar.
