I'm a bit stressed so this will be a short one, but here's something I want you to concider, since I think it's a quite interesting question because the opinions are so extremely spread. So:
Battlefield or Call of Duty? Why do you think as you do, what could any of the developer teams improve?
It's one of the biggest debates in the gaming community, but with Battlefield 3 incoming, the discussions are hotter than ever. I refer to the game series as a whole, not just the latest games in respective series.
