What is the Best Online Multi-Player Game? [POLL]

Remember the days of just playing video games against a computer? It was cool, but not as fun as being able to play your friends.  Nowadays you don't even have to have them over to the house to play so they eat up all of your food.  Just play them online in a mulit-player game.  But, which one is the best?

Sometimes I'll jump online and play Madden '12,  but most of the time, you'll catch me playing any of the Call of Duty games...especially Call of Duty: Modern Warfare 4.  Even though I get my ass kicked most of the time, I just like jumping online and playing with real people.  Plus, I have friends who don't live in Abilene, so it's a fun way for us to connect, rather than texting or talking on the phone.

So out of all the online multi-player games you can play, which one is the best?
