In the Platform Builder EULA it states that games cannot be sold. I recently contacted TingThing about this. He says it is perfectly fine to sell Platform Builder games now. Why? Because you couldn't sell them before because PB uses purchased resources of which they cannot be resold. But now you can. As long as you don't use those specific resources. Now, if you export to exe using the UPE, you can sell the game. The UPE automatically removes those resources. So, in a sense, this is from TingThing.
