Wow, only now do I realize how long it's been since I've played/hosted a proper LAN party. Those were probably some of the best times of my life right there. My brother and I were fortunate where we could get a bunch of people with PCs and laptops over, so we would always play a myriad of games, from Warcraft III/TFT, Brood War of course, CS 1.6, UT2k4, Quake 3, and especially BF1942., Star Wars episode 1 racer.
If we had too many people over and/or people wanted to opt out cause they didn't like the game, we had a TV set up with an N64 and PS2 for whoever wanted to play goldeneye, Mariokart 64, timesplitters 2, etc.
We did that almost everyone weekend when I was younger. Also some of the best moments of gaming with friends have been on Halo 1, when we would set up 2 X-boxes and play 4v4, and one time one of my good friends family had a night where they would play Unreal:gold over LAN, and we had enough computers and people to play with I think 9 or 10 people
God I miss those days now, so very much
