For some reason, Infinity Ward could not predict how many people were going to buy this game. (Seriously - how many online CoDs have their been, take a ******* guess) Atm the servers are very, very unstable, like every CoD in its early stages. Give it time and it should fix itself (This is assuming you have no problems with other games or the campaign in this game) EDIT: If you're playing on PC (you don't specify) turn down graphics.
It also happens to me but in the regular multiplayer.
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.
