When picking up Oddworld: Stranger's Wrath on PSN, I also grabbed Rayman Origins on a whim. I'm not a big platformer guy anymore; "my series" when I was a kid was Mega Man, and I still think Super Mario Bros 2 (the Doki Doki Panic one) is a better game than Super Mario Bros 3, so I suppose I'm kind of the wrong guy to judge a pure platformer. But dang.. Rayman is really something. I can't put my finger on it, but there's something about the model where you can invest as much as you want, and have a great time regardless. Granted I haven't gotten very far yet, and I'm told it gets brutal, but for now anyway it's just a joy to play, and I love it when a game lets me choose how much I want to challenge myself.
The only thing I'm not crazy about yet is the collision detection on some enemies. It's kind of hard to judge the exact position you have to be in to land on something, so the general feel right now is to just try and land on the middle :-P Reminds me of Little Big Planet in a way, and not a good one.
