Gears 1 also had the best soundtrack out of the two! I missed the first game's main theme when playing Gears 2. :(
That's why I play Gears 1's soundtrack when playing multiplayer, it adds a lot to the experience!
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
