Very cool idea. I was a big fan of Quake 2 and played it for hours on end both offline and online (LMCTF mainly, some RA). I also used to build maps, yeah, I was that into it.
It’s basically Quake3 given to you for free with online matching services. Pretty interesting idea. If you head to the site (below) and take the virtual tour you’ll get an idea of what is involved. Pretty cool idea, even if Q3A is a little old.
