Honestly get Bad Company 2 or Reach both are actually new and not a carbon copy of the previous games like the COD series. I love COD but all you do is multiplayer, which is filled with little trolls and hacks and grenade launchers, at least the other two have more interesting stories and require more skill and not having a rocket launcher kill you every minute. Fyi I plan to get all three and MOH which will be better than Black Ops.
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.
