O.k. I think you should really watch what your saying. You are being extremely rude.

I know that id Tech 2 is free to be used in commercial projects under the GPL or Non-GPL for $10.000 per title(http://www.idsoftware.com/business/idtech2), but I didn't know anything about Quake 2 artwork & models being open source.

Anyway if you post something for download you should expect questions about possible usage.

...and I have no idea what garage-project means. If models you posted are open source where is the txt file that contains license?
