Oh crap this thread made me feel like an old bastard! I was in high school when Quake came out which meant that basically any class room with some computers enabled us to have some fun over LAN. It was also one of the first games that I played online with my trusty dial-up connection. The game had some serious legs, thanks to a pretty awesome mod / total conversion scene - made quite a few mods together with my friends back in the day!
