This really is a very cool game to play!
I can recommend everyone out there to give it a try on a windows or linux box with a good 3d accelarated graphics card and the right drivers installed.
It's also very cool as a lan-party game with people joining from both the internet and your local network. The server can run on *any* old computer with windows / linux and can serve request from anyone from the internet as well :-)
Give it a try! Have Fun!
