I was at cybernet cafe memphis, and we had a little Q3 tourney. Now, a few years ago when the quake III demo came out, I was hooked, but I didnt have any connection and I never bought the full version, so I played against bots all the time.
I ended up mastering this demo, and I knew where all the bots would be. It seems like it is the same thing with newbies. I had a friggin 100-5 ratio in the end I think. Same in Jedi Knight II.
