I'm not going to bother checking my facts on this one, cause no doubt someone would and could argue it either way.... but I think most games are made for fun and entertainment, which I'll freely admit includes people;P...
However, like the Beamer, I prefer bots with most games. While I don't give a shit about CS, although I do have it on here, I typically play Quake 3 against bots. It's like playing MS Freecell.... doesn't take any time to set up, my machine these days runs it with all the ease of Freecell and, ultimately, I just want to kill a few minutes shooting something before reality requires me elsewhere. So, I get my fun, which is what I want. I also get it faster than I could get any game online.
Whether you come across cheaters or dickheads, there's plenty to put some people off online gaming. There's also the simple fact some of us just can't be bothered with it. So what.
