How many people are on forza motorsport 2?

on the avg, bout many people are online usually, and what else is a good game to get with alot of people online? or a good gaming community?

I find its a great game for single player but mainly if you go online youll find people who just want to drift unless you get into some sort of tournement. However they do have a great webiste where this is loads of people who follow it. Not many other games that are like it for racing, if your really into online games just get a halo or call of duty game, way more people on that ****MikeHawke
