I'll be very interested in seeing what the uptake is on this - from my experience, Unity is the most popular because any idiot can download a bunch of assets and hack together a load of copy-pasted code - or worse, reskin a "complete game" asset and try to pass it off as their own work - and float their abomonation on whatever store in the utterly misguided belief that they are going to get rich.
