Only the PS3 was hacked just so you know Owen. I would say MW2 is better. More things to do online.
Black Ops is so laggy and everyone just camps with Ghost in a corner all game. By the way. Infinity Ward is making MW3 which is supposed to come out in either 2012 or 2013.
The next Call of Duty game is being developed by Sledgehammer.
First of all, Mw2 has been recently hacked and it is nearly impossible to NOT get in a hacked match. Second of all, Boosters are taking over. So I say Black OPS because you can't really boost and it's nearly impossible to hack, except for a few exceptions such as gold gun hacking.
So I would have to say 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.
