I really do not know, it is easily in the millions total, billions I don't know about, I know how much a billion is and even though I know how much video game carnage I have wrought I doubt I have wrought that much, even with homebrew maps and modded weapons and cheat codes and all of it, billions is huge, definitly people who have, I just don't think I'm one of them.... of course, I had 2000 hours on GW in a year of play, so there we go, I might be one of those people
edit: and we might want to look at the other aspect, the higher your age:kill ratio the more nerd\geek one may be, the lack of life required to accrue such ridiculous counts can be... restrictive
