Server browsers and dedicated servers are subjects that make me want to start with the old man “back in myyy day” style comments.

I saw somebody mention CS, which is a good one, but for me the peak was in Quake 2 because of personal circumstances like getting into overclocking and then moving to a university network connection when modems were the norm at home.

Certain servers running certain mods were awesome late-night hangouts. I have a few really fun memories of all of us coordinating to do goofy stuff rather than play whatever the game at hand was. Then somebody new would join the server and start wrecking us until we caught their attention with the text chat and got them involved too, lol.
