Sorry acs, never got into the whole FPS thing.
Well, actually, I was addicted to Counter Strike for a few years, during which time I played Half Life extensively.
But CS reached a competetive level at my college to a point where I couldn't stomach it anymore. One day I just uninstalled the damn thing and never looked back on FPS's.
I played Halo with a friend a few weeks ago. I sucked.
It's ok, I'm happy playing CivIII until the cows come home.
