Ah, when I said "free" I meant it more in the likes of "being free of getting sued if you casually throw stat blocks built with said game's rules on free/cheap short fantasy stories you've written on the Internet" kind of thing.
Apprently I heard the infamous TSR in its latter half did just that (and will never do so with GURPS stats, otherwise my favorite level of granuality, as I am quite scared of how SJG might react)...
