Rayman Origins is, simply put, absolutely delightful.
I say delightful because every time I boot up this game and let the gorgeous visuals and bizarrely brilliant soundtrack wash over me, I just can't wipe the grin from my face. The game's not all looks and no substance, either. Under the shiny veneer lies a tightly-made platformer with plenty of challenge, hidden secrets, insane humor, and great variety. Overall, if you're into platforming at all, you will find plenty to love in Rayman Origins.
I've never been a huge fan of Rayman. I've played the underwhelming original that looked nice but was too slow-paced for me, I played the second one way too long after the fact and just can't hold it in the same regard as Mario 64 or Banjo-Kazooie, and I never got around to trying out Rayman 3 even though I heard generally positive things about it. It surprised me then, after trying the demo for this game, just how astoundingly entranced I was with the experience.
Let me make short work of this: the controls are silky-smooth, the visuals are simply unmatched in the 2D realm (I didn't know they could look this good!), the game is chock-full of silly humor (pig latin anyone?) and sexy nymphs (heck yes) and hideous-yet-still-awesome-and-sort-of-beautiful bosses that take up more than the screen. There's always plenty to do with tons of levels, speed run challenges, medals to earn, shoot-'em-up style levels, and more. It's just such a fantastic game that I can't recommend it enough. Go play it!
