This thread is pretty jacked. I think the OP just wanted to give people the heads up for a price drop on this game, one of the lowest since launch, and people certainly aren't appreciating here.
Is this rehash game worth $60 or $45? Certainly not, except for the fans like myself who paid $60 at launch. Is this $45 deal for everyone? No, it's for the semi fans. If you haven't picked this game up for $45 or $60, you are not a fan of the series and you have the right to wait for the game to drop to your desire price, but just don't bitch about $45 is not a deal because that's the lowest price since it came out.
Stop comparing this to shooters. It's apples and oranges. In a market dominated by 70% shooters, a game like this is greatly appreciated.
