As for the topic:
I gotta reiterate on Skitchin'. Just a lot of fun, if you can get into it(that's the key part of all of gaming, really).
I've tried all sorts of games in the meantime, but 5 pages in, and I don't feel like looking to see if someone else has already listed something I could mention.
