Bioshock - Have you played this?
 

This is one of the best games I have ever played. Great storyline - insane graphics - non-stop action.

Its truly twisted as well.

The whole "big daddy" and "little sister" thing creeped me out. I was almost expecting a visit from Chris Hansen.

Yeah I agree on that one - having to choose between saving and harvesting the little sisters (harvesting makes you stronger) is very creepy. I heard that when you finish the game your decisions actually change the outcome. still ahve a way to go - stuck in a hard level.

Fantastic game. But do your business a favor and step away from the controller. I lost a whole two weeks playing that game. Just couldn't stop.

Yeah... played most of it on 360! Insane game!

I played that game on my xbox 360 and finished it. It's a good game.

I would say best game since the original Grand Theft Auto. I played that one for a month straight. I dont have time or dedication to paly like that anymore - but I really like a game that has such a multi layered storyline and sub plots.
