Is it possible to have a multiplayer deathmatch game of Quake or Quake II without buying any software? I keep seeing things about Quake mods, or OpenQuartz, and I know that the Quake and Quake II engines are now GPL, but: can you just get and play a game? What I want is just a downloadable game that I can install on a load of machines and then have people do deathmatches. That’s it. Is it even possible to do this?
