I thought I'd bring this back up, in part to remind people to play this game (if you are on this forum, chances are you like platformers and this is a real goody), but also because I wanted to mention that I have finished the game and since found The Land of the Livid Dead. This is the super-secret world that's opened by beating all of the fiendish treasure chest chase missions.
Let there be no mistake: at the start of this game, it's a little bit of a slow burn, perhaps because it somewhat unnecessarily rolled out Rayman's moves gradually. Trust me though: soon enough, you're sprinting full pelt, jumping with split second timing through small gaps as the ceiling falls and the spikes jut from the floor. At times, Rayman Origins is brutally difficult, but in that immensely satisfying way, like DKC Returns or Super Meat Boy.
I'll also add that this probably wins my personal Best Soundtrack of 2011 award. It's not really even a contest. Games that use extraordinary styles of music to great effect get top marks in my book and very few do it quite as much or as well as this game. If this selection of music doesn't make you want to play Rayman Origins, then I give up and conjecture that you hate fun.

Oh, Ubisoft... if you'd only released this some other time. It was one of the busiest Novembers of all time; if you want your game to be noticed, that is not the place to put it. I don't have a problem with it being a retail game, as it's easily got the chops in that regard.
