I just hope it's not too restrictive now. I mean, in the end the shop is meant to be profitable. But with too much restrictions, people may consider to not buy. I'm happy that music is not bound to a certain format. But if I read about the ebooks... Imagine a teacher having interest in an ebook to use parts from it in his class. He/she would have to buy 20 (or however many students there are) licenses of the same ebook! I think this will lead to the decision to better buy one printed book from another author in a local shop instead.
Also, the commercial project declaration is still not so obvious to me. If someone creates a game with graphics bought in the shop and then sells the game for pc, it surely is a commercial project. Half a year later, the game is so successful that additionally a free version with ingame-ads is published on (Kongregate/Armor Games/Fill in whatever you like). Now is it still 1 project? And if not: where is the threshold?
