Re:Quake I (Score 1)

I have been playing co-op Quake with my brother recently... and Ive also expanded my Quake 1 to a whopping 5gigs... well, thats a huge amount of expansion for a game that was originally under 60megs. id has released the source and John Romero has also recently released all the original .MAP files from the games production, including a portion of a map that was cut to save space!

The quake engine has been redone, modded and theres still quite a bit going on with that game.

The short version; Visit: http://www.quakeone.com/

They also have a list of current active Q1 servers that detail player count and current map/mod being run.
