They're so different...

Vegas builds a nice, tension filled environment where as Gears of War is in your face action that just doesn't stopped. I like em' both.

yeah, they're totally different. I just prefer the rainbow six style I guess, I'm also terrible at gears of war. :p

I'm bad at rainbow six too, but atleast I can kill people.

Doom,And doom 2 came on my doom 3 game.I'm trying to beat doom 2 on the hardest difficulty It's hard.

Hell yeah, man...
I still have trouble going back to the "old" control system (unless the versions that came with doom3 implemented mouse controls?), did it a couple of years ago, and I'd never played through doom2 before, just messed around with it. When you fully throw yourself into it, graphics aside, it's actually a pretty scary, and intense experience. The music and sound effects are brilliant, and the gameplay (hard mode or not) gets VERY crazy.

Yeah,doom 3 scares the crap out of me,when you hear a zombie moaning and you don't know where it is that gives me the creeps.

Haven't had the occasion to play very far into doom 3 yet...maybe sometime soon, I dunno...

I'm probably gonna pick up the expansion pack after I beat the game.

Are either one of those as good as Halo?

Rocky legends.

both are better in my opinion. :) (and totally different)
