Fahrenheit.
Which started out pretty cool, until it got ridiculous with the lengthy QTE and WTF story elements. Spoilers if you care:
[HIDE]Like, WTF. The female detective you play as FALLS IN LOVE with the main character, who by the time she actually meets him is a REANIMATED CORPSE that was brought back to life by an AI?!?! Oh, and then they FRIGGING DO IT IN A TRAIN CAR. Yeah, DOINT IT WITH A FRIGGIN REANIMATED CORPSE. AN ICE COLD CORPSE. They knew each other like, FIVE MINUTES. Way to look mature video game - throw in a totaly pointless sex scene. :redface2:
Oh, and the special pure child that knows the secrets of the universe and your super powers and the AI that wants to take over the world that comes out of nowhere. whaaaaaa.[/HIDE]
