I really like the flight simulator marketplace. There are so many addon providers that Asobo couldn’t manage. Asobo earns money with every sale and users get more content in less time. Its a win-win.
I could imagine that third-party providers could develop and sell race tracks. Of course you would have to define some quality criteria. Such as licensing issues. But I think these people could potentially develop and publish lesser-known routes much faster.
