A game with best multiplayer...

Which game has the best multiplayer? No matter what genre just online multiplayer.

My choice: Battlefield 2

Unbiased opinion: Halo 3. I hate the game now but I have to admit it does have fun multiplayer. It's so fun to go on with a group of friends and just talk trash and mess around. My personal favorite would be Call of Duty 4 because of all the customization of classes.

bf2 is my choice as well. i also like css, halo 3, gears 2, and pdz.

For me it would be Rainbow Six Black Arrow, old school. I had the best times in that game! But why not do a ranking: Top 5

1. RS Black Arrow

2. Left 4 Dead

3. COD 4 Modern Warfare

4. Halo 2

5. The Ship (If done with a lot of people and correctly)
