If you looking to sell your games, then you may be dissapointed by the quality of most of the free media that is available.
Banshee Studios provide free-to-use media for non-commercial products, the quality is reasonable - but if you where to take that and make money out of it, is that fair?
I would argue that it wouldn't be fair, and i'd therefor expect any product selling using Banshee media to be splitting their royalties fairly with us.
Banshee is willing to listen to all offers for code and media.
