DO NOT GET BATTLEFIELD 3! I've been playing the beta, which you should too, and it is complete trash. It's nothing like I had been lead to believe and it's just a horrible system with weapon classes and how you customize things.
MW3 is going to be outrageous, they've made so many changes and better things to the new CoD and it's going to be great. Also, the graphics in BF3 are NO WHERE near as good as had been previously stated, they actually kind of suck compared to other games coming out.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
