Probably the most underappreciated game of 2011, Rayman Origins is absolutely wonderful. From the beautiful 2D art style, to the soundtrack and humor (in a game that has very little dialoge), Rayman Origins is worth checking out.
It's also really hard at times! Take the 'Blue Baron!" achievement for instance. To get this one, you have to beat the Blue Baron in under 60 seconds. Good luck!
If you somehow manage this feat, you're rewarded with a silver trophy on PlayStation 3, and 35G on Xbox 360. Wii owners will get shafted, as they don't get achievements. Sorry guys.
