Non commercial licensing makes perfect sense and i don't know why two major marketplaces still don't offer such possibility. More and more marketplaces offers non commercial licenses now. I think CGT should take initiative in their hands and introduce dual licensing. Then TS most likely would follow, because it seems that they like to copycat CGT lately :]
@iterateCGI, i think introduction of proper non commercial licensing instead of mixing it with price offer, would be preferable, because in the latter case that option might go unnoticed by buyers and also it could make a some confusion.
@DUST, yes, no one can guarantee buyer won't abuse licensing, but on the other hand no one can guarantee that he won't choose to search for pirated "free" version of your or similar model. Those who don't care about licensing, usually aren't willing to spend a penny on a models if he can get them for free. I think there is a lot of people who won't use illegally obtained models because of moral constraints, even for personal projects. And for those people to pay for commercial license might be bit too much when all they want is to use model privately. Why don't give them a chance? That even might be a next big boost in sales, especially since hugely discounted sales became everyday norm thanks to desperate actions from CGT.
To CGT team - i'm all for non commercial licences! Give them to us or at least explain your position about it.
