I think there's a fine line between what should be free and what should be charged for. Being in the software trade connected with PDAs the authors of that software are aware what is considered freeware and what is considered sharware quality. The artists have to make up their own mind as to what they charge. I cannot create models and textures, I am not that skilled, so I rely on other people's stuff to create my artwork (which is just my hobby). I am more than prepared to purchase these items, so long as the price is reseanoble, I say good luck. But that fine line must be observed, Quality is what will make you money in this kind of game, not quantity.
