I looked at the screenshots and stuff. It's a huge aggregation of a bunch of (presumably free) existing content, including textures and levels you will probably recognize. For example I saw a retextured version of an RPG speedmap here: http://qexpo.quakedev.com/uploaded/17/weapons000012.jpg
It also appears to have some non-free content, such as models recognizably ripped from quake2 and the UT series.
It also doesn't appear to be a true TC, as i see stock torch models, a knight model, and stock HUD graphics.
Those comments aside, it would be interesting to see what all is here and how it plays, since it claims to be a huge game (6x15 SP levels?)
