Something like 85-90% of all gamers play only the single player game.
BULLSHIT
90% of Those 'gamers' are 5-10 year olds , and the rest are idiots that think the 'net' is some government project and refuse to get inet access.
I wouldn't want to meet anyone that (in these days) would still sit around and play with himself against a bunch of scripted idiot computer characters.
