Minor Nitpick: Xonotic isn't a clone of Nexuiz, Nexuiz was the original name of the project until the project originator sold the name and rights. This caused the community to fork the project from the last stable version and continue development with the new name, Xonotic. Today Xonotic has a small but passionate community whereas Nexuiz languishes in obscurity.
I didn't know the "real" nexuiz still survived! It was cool to me because I didn't get to enjoy the unreal tournament days and had some interesting maps.
