redistribution rights and usage rights are very different things, i'm sure we're all aware. i personally am thrilled every time i see something i've created being used by another artist, whether it's a simple image, or a commercial image, or whatever. i would be thrilled to death if someone put something of mine into a popular game or (omigod!) a movie!!! i've already had a couple of requests, done from common courtesy, not usage stipulations, to use different things in some independant games. i was happy to say yes, thank you kindly for asking! it's creatively stimulating to me when someone else can make use of my creations! it's a natural high :) i think many of us would and do give permission for games and such simply for the thrill, and the most compensation asked for would be credit given.
