begin excited ranting:
Street Fighter 4 looks really good with that over the shoulder view, but I am too much of a wuss to start manhandling a new system with crazy combos. I don't want my slider to get chunky like an N64 controller. I'll get over it soon, I really want to beat people up online.
Samurai Warriors is what I'm playing most. It feels pretty complete, and I heard that there are downloadable quests and local versus modes or something.
I still haven't gotten past the first mission in Ghost Recon because the 3D effects trigger my ADD and I just daydream about how neat everything is. What I have played combined with what I've read is totally doing it for me though.
I got Sims 3 and Bust-a-Move for my girlfriend... strangely, she isn't sure if she likes Sims 3 or not yet either. I took a picture of her butt in 3D and she got mad.
Besides all that, the AR card games are amazing. It's creepy as hell staring into a hole in your floor that you know does not exist. I hope we see ideas like this develop more.
