Yeah hit me up with them, I will def. use them and if you have any input on the achievements please help me out lol gamestop said they shipped my game out to me but I never got it. Still waiting for it!
To be honest, I've never noticed a difference between any of the games, but apparently the engine is like Decades, much to the dismay of people. The game kind of sucks in all honesty though, well the UK one at least, the best song we got was Scream Aim Fire.
I got the US version and that's better but the career sucks, making you play each song about 3 times to progress.
