The architecture looks amazing, and the monsters too! Is this co-op? I only played Quake 2 once... (wait, this is Quake 1?)

This may be me reading into it too much, but it's really cool how these old games have become kind of timeless platforms for content (doom too). You don't need a billion polygons to express lots of ideas and it reduces the effort required to contribute, and the open source-ness of it makes it available on lots of platforms, irons out lots of bugs and issues, etc.

Another amazing piece of gaming and art by an incredible, dedicated community. I'm thoroughly enjoying it so far, and I've still got a long way to go.
