skate - I don't know why it's supposed to be lowercase, but this game rocks. It is the closest thing I've seen in a video game to actual skateboarding. This is great for those of us that are sick of trying to mimic real life tricks on rooftops or other ridiculous high platforms in the damn Tony Hawk games. Manuals take a bit of getting used to as does getting into grinds, but it's really fun. I have a bit of an issue trying to do some tricks - 360 flip for example - where my character just keeps doing shuv-its. I really want to see a non-park level to get an idea of how good this is going to be.
Bioshock - Pretty Damn Impressive. That's the best way to describe what I've played so far. This, (and skate) are games that actually look good graphics-wise on a standard definition television. The controls seem good (although if I tap right on the right stick, it has a tendency to keep floating off that direction.) I was worried about switching back and forth between plasmids and guns, but it is actually very easy. The enemies are my only real complaint so far, as they all look pretty much the same. But I guess I don't need a wide variety of people to hit with a wrench.
Both of these titles are shaping up to be pretty enjoyable (although since I've got them much of my time is still being spent playing Super Metroid) and hopefully I can find more 360 games that I like this much.
