I don't want to play a game that was totally different than the other but now is still "similar".

Halo 4 is more alike Call of Duty than Battlefield is the Call of Duty. That's sad.

Call of Duty used to be nothing but serious FPS until it's downfall happened, Call of Duty 2. Main reason why I dislike CoD. The smallest map in CoD used to be Carentan (China Town in CoD4) now that's the average size.
