.. There is still lot more.. but.. cant really even remember all xD

Ed, I play NHL 12 very often, but on my PS3. :C EASHL ftw.
NHL is one of my favorites, if not the favorite.

I got Alan Wake.


...I'm too much of a pussy to play it.

Lol, Dead Space is scarier.

I bet, but Alan Wake is already too much for me.
Also, I ruined episode 1 by watching a playthrough.
YEAAAAAAAAAAAAAAAAAAH

i love alan wake, specially at night with all the lights off(no homo)

Yo brah should I get Skyrim or Mass effect 3?
I got the Mass Effect 3 demo and it's hard as fuck.

How is that homo? On a second thought, don't answer that.

I'm thinking of getting The Darkness II. It may suit me better than Alan Wake.
Any opinions?

the darkness II is something i would recommend. excellent gameplay, lots of carnage, and you get to play as a black guy using a voodoo stick.
