Old games with dedicated server
I've been brainstorming a bit about how I'd set up a LAN party.
Right now I'm looking for games from the late 90's and early 00's that have a dedicated server variant that I could host in a central server.
I know of Unreal Tournament, Quake 3 Arena, OpenTTD (not totally retro, but based on a 90's game), but after those I'm a bit stuck.
Anybody have good suggestions?
