I detest the way ubisoft go out of their way in every game they make to remind you at every opportunity that you are playing a game.... I initiate a conversation with someone, and the screen starts flashing white before you start. I complete a mission, the game pauses and a large black box covers half the screen to tell me a load of useless information. I simply walk along the street, and guards, merchants etc have a white glow around them and flash when you approach. I simply don't understand how they could think it is good!.. Oh, and you can't simply blend in with people as you stand near them, of course not, you flash white, and a weird sound plays.
They do it in splinter cell and far cry as well.
