I am not too big of a gamer, but I have a few I get into. I was just looking around on the web and found some good dedicated gaming servers for linux, that of course run in a CLI.

Now, I just wanted any suggestions on what games have a dedicated server for linux. I need to know how much it costs (if anything), how much the client costs, and what OSes the clients run on, plus minimum system requirements for both. But don't worry, I will find out the rest if you guys can just supply me with a good list of these games

Building a box for LAN gaming with some friends and need some ideas.

Already:

NeverwinterNights
Unreal Tournament 2003
Quake
CounterStrike

Those are all I can think of, and some are also games that are also linux supported. Im sure there are more out there I don't really do a lot of gaming so I don't really know...

Diablo
Diablo II
Diablo II: LoD
Age of Empires
Age of Empires: Rise of Rome
Age of Empires II: Age of Kings
Age of Empires II: The Conquerers

Then if you could somehow get the source for it:
The Realm
