I had an absolute blast playing UT and UT2003 in LAN matches. But discovered a crazy thing. My main PC was a Celeron 700 MHz (Coppermine) and I had a spare Pentium (maybe 133 MHz. It's all hazy at this point). The matches were fun and I was winning often enough to keep me interested in going. Then the other guy bought a P4 Northwood 2.4 GHz and suddenly, I felt like a chicken running for my life. I would frantically do 360 degree turns and would only sometimes catch glimpses of my opponent right before I got slaughtered. And of course he refused to swap PCs. That made me lose interest pretty quickly. Both PCs need to be similar in specs otherwise you won't even see what hit you. And online play is all about lag. The only online game I would play is turn based strategy against another human. Don't trust fast paced multiplayer action games to be fair due to the crazy amount of external factors.
