i own halo and a 360. i played halo 3 for a week, got mvp in every ranked match (prolly cuz i was playing a bunch of noobs at the lower ranks, but i was too bored to continue on). the game is, like an above poster said, perfect multiplayer for consoles. i couldnt complain, yet here i am playing cs 1.6 released in 1998 and earlier if you count the betas with a 400+ dollar game system sitting behind me. pc just delivers a MUCH better multiplayer experience. therefore, halo is overrated simply because most people dont know how to install a new video card or RAM in their pc to see just how much better pc gaming is. to console players, halo is GREAT. to me its fine, just not nearly as good as any of my pc games. buying an xbox360 was the biggest financial mistake of my life so far.

oh and to another above poster, id like to agree that halo is fun because of the social part of it. like every kid in my shool (well everyone im friedns with or even just in good standing with) like 60 kids play halo 3 on xbox. i bought it to play with them instead of random cs clans (one ive been in for 2 years and is more friendly) or WoW guilds. i play WoW though and find if you have a good guild you can get into some incredibly funny and random conversations, or on cs clan forums threads go NUTS. the social part of halo can be had on pc
