It's happening again

Halo is taking over my life. Well, not my life, but my gaming life. I sit down to play video games, and what do I do? I play Halo. I'm in the middle of Gears of War, Metroid Prime 3, and God of War, but it doesn't matter, all I want to do is play Halo. All three of those other games are awesome, I just can't seem to pull myself away from playing matchmaking or the meta-game in Halo. It's like a drug...
