tiz' cool, tiz' cool.
I ran into the same thing with Halo 2 years back. Me and my friend were always at his house playin everyone in Multiplayer. We made like 3-4 clans, til' we finally grouped together some decent players who weren't children.
Then we graduated and went back to Counter-Strike. He stuck w/ 1.6, I moved on to Source
Lesson here is...you'll eventually move away from Halo 2.
Btw, are there still a butt-load of hackers, modders, dudes who stand-by, children who talk smack, people who spam n' what not? Those were the reasons we lost interest.
PS3 will be there with open arms ;D
