Future list of games we COULD host on Cyberix soon:
Suggestions taken by people from around the web.

Source mods:
 The Ship, Zombie Panic, Zombie Master, The Hidden 

Return to Castle Wolfenstein
Half Life 1/2 mod like Sven Coop or Synergy

Quake Wars (vouch 2)
Fuel of War
Tuork 2 (vouch 2)
Cossacks 2
Rise of Nations (vouch 3)

WarCraft 3 v1.26a  (vouch 2)

Serious Sam co-op

UT99 and 2004  (mod's like Unwheel to spice things up.)

DOOM and it's ilk may be overplayed, but something like the original Marathon, which is also free
DOOM (Vouch 2)

Tribes 2 (free as TribesNEXT) or BF1942
 battle for middle earth because it's abandonware (meaning it's free) and there is now an all-in-one launcher for fanpatched vanilla bfme1+2+rotwk as well as a standalone age of the ring modded game based on rotwk.

command and conquer 
twisted metal 2
quakeworld
Civ 2
Urban Terror (We have this)
Mario Kart in the Dolphin Wii Emulator

C&C-RA2
(Command &Conquer)

The open source version of the original Command and Conquer games? Both Tiberian Dawn and Red Alert

'Thievery' mod for Unreal Tournament (yes, the first one)
^ description: "It's basically multiplayer 'Thief' with thieves and guards vying over valuables, and the gameplay is like nothing I've experienced before or since. Very unique feel, maps are great and the cat & mouse dynamic makes for a perpetual suspense.

Teamwork has obvious advantages and wacky shenanigans are likely, so it's well suited to a casual community game-night type of thing.
"

Team Fortress 2
^We have the... 2008 version

James Bond 007: Nightfire
The original Battlefield Vietnam


Things to prioritize:
Games that DON'T require us to purchase them (Games that are pre-cracked or FOSS remakes available count)
Games that can also launch on Linux, but it's okay if it can't, but puts it lower on the priority scale. If it runs on WinXP it's okay but if it can only run on anything higher then that puts it even lower on the scale
Games that have easy-to-setup servers (If it has a Docker container, it probably is easy to setup on its own, for example)


We'll need to find download links for the games to put on the game's index page but its okay if we cant acquire them. Having the servers up and running is top priority before finding the links if both can't be done at once
