Just got a new Elite, quick question

I just got myself a new elite, and was wondering what MP game has a strong community still? besides COD (i have MW and WOW on the ps3).

thanks for your input

Grand Theft Auto IV.

Halo 3, Left 4 Dead.

Battlefield: Bad Company. But trying to find people on there with mics is sorta hard.

GTA IV also always has loads of people on there.

yeah i was thinking of getting halo 3
