Okay, since I like Halo 2 a lot, and I like to be a part of a team who works in conjuction with each other, like my soccer team, I decided to join a clan. Clan's are really just people who like to play video games with other people that they know, so it feels comfortable to talk about different matters. And the experiance of playing and beating some one you know has a better "winning taste".
Anyways, here is my clans forums: www.str8pwnage.tk
Halo 2 revolution the gaming world, with it's amazing graphics, high re-play value, awesome game play, and of course the ability to play it over xbox live, which lets you play sometimes friendly matches against people around the world.
That is my opinion, I play Halo 2 way too much, like maybe 3 hours a day. I know that seems like a lot, but I know people who dedicate 10 hours of their live everyday to Halo 2, I think that is very un-healthy, but hey, that's what video-hating parents say.
