Eh. Not everyone's amazing at it. You don't have to play it if you don't want.
I always played halo CE in school with my friends on the mac. Yeah, it's a demo, but multiplayer on such an old game is really fun with friends. I'm decent with FPSes on a PC... or mac rather.
Yeah I found a crack for it, but the multiplayer servers are lacking, and it detects the crack when I share it with my friends to play online.
