I second the Orange Box suggestion. there's a whole mess of games there.
I can also appreciate why people wouldn't get anything out of bioshock, it's not a COD type of game, it's about weird shit that deals with weird shit. Would you kindly give it another try? Let it take you over?
That's right, I just did that ^_^
Man - I need to play it again.
I still don't get why people don't like Gears. I really don't. I swear to god if I could marry any game, that would be on the top of my list. Maybe I just like my comrades to swear with reckless abandon, or I take much out of popping someones head with a sniper rifle, blowing their legs off with a shotgun, or cutting them in half with a chainsaw.
Now where's child services when you need 'em?
Other games? Assassin's Creed is cool, and cheap. GTA IV is just... Well, it is
If you no haz liking that, then well - there's not a lot left!
