to answer your question, I find that obsidian has a solid fanbase and reputation, and I'm looking forward o playing their future console games, I would have gotten NWN if it was for 360.
I really hated that game Nick. The game got tiring for me after the level where you kill the bug that killed your dad. It was like target practice. Go here, bugs come out of snow, shoot orange spot, repeat. The multiplayer was for a while.
Why don't you get out of tADS and go hang on your IRC channel. We'll meet you there. ;-)
EDIT: Way to edit your post and make me look like a jerk.
I mean a bigger jerk.
Eh, I don't really have a favorite. I played the crap out of Crackdown, but that was only because it was Co-op.
Not saying it was my favorite game, but just that it kept me entertained for a really long time.
