BF3, MW3 OR BOTH?

I know I should play Battlefield, but honestly I pre-ordered Modern Warfare 3 and that's all I'll be playing for the foreseeable future.

I'm getting both, Any Shooter games make me happy :D

Although battlefield 3 and MW3 are two completely kind of games (Arena matches vs huge battlefield) i prefer battlefield 3. I like war games with huge maps, vehicles and objectives. Battlefield 3 is perfect for it, although i still love playing battlefield 2 for PC, one of the best shooters to date in my opinion. Graphics aren't so appealing to the eye, but thegame playis. My favorite Call of duty game is MW1, it was pretty decent.

They're both different games and both good in there own ways.

Yeah they're different games, all about opinion really. Survival mode looks cool by the way.
