Here's a question I've always had with this. I'm not trying to be critical its an honest question. Why can some companies develop add-ons and sell licenses for those add-ons that work for both products, EX, Carenado. I can buy a Carenado aircraft and legally install it in either P3D and/or FSX for one price. Yet PMDG has to have two separate licenses for two different prices. Again, not criticizing at all, its an honest question.
