I'm thinking about downloading some X-Box Live Arcade games when I get home this week. I played N+ at a friends house, it was fun, so it's probably in. Any other suggestions?
Puzzle Quest is the best game hands down. Ikaruga and Carcassone are good. Mor is a huge fan of Bomberman live. I like Assault heroes too.
I picked up Puzzle Quest last week ... Thus far it's been pretty dang addictive, even cutting into my GTA IV time.
