Metal Cord (Metal Chord? Something like that iirc) looked very interesting. If I've got the name wrong, maybe someone can help me out by reading the description. For all I know i've got it completely wrong.
Anyway, Metal Cord (or whatever its name is) is interesting in the fact that you don't actually control the character per se, rather you uh "make suggestions" as to what you want him to do and maybe he'll feel like doing it if he's happy with you. The example offered on the page I saw the preview of this game on was this:
There's a cave. A big, dark, scary cave with bones and blood all over its entrance. The player tried to get his guy to go in, and the character's response was "Fuck you [username]! No way in hell am I going in there!" followed by a decrease in his "affinity meter" and him getting grumpy.
I'm not even sure what genre the game was, although it looked like a third-person shooter.
