I would like to see an aircraft modelling toolkit so that 3rd parties can create aircraft but have the game engine set up so that they are approved officially and can be used in game.
Then they could be sold/licenced like the Rise of Flight model. This would be a great way to expand the sim flyables at minimal cost but higher revenue for the developers. As in Rise of Flight if you do not have the licence then you do not fly them.
I'd buy the lot.
