I have no doubt Microsoft would like to “reuse” the flight sim into a shared sim world. The synergies are obvious and lucrative in dollar terms. There is endless scope to make addon income like GTA. And not only a shared online world but a persistent shared online world. By persistent it means changes stick and get carried over in multiplayer and next time you log on again. So that for instance the grass will grow longer in summer but if you mow it is noticeably shorter and also when you come back the next day! If you paint your mansion or replace the roof then likewise it will persist. If you leave your Mustang parked outside it will be there when you log on again etc. No there should not be crimes or stealing but there could be a penalty with dollar amount for driving through a red light etc. Or you don’t make it to the airport for your scheduled flight you are fined or suspended from the airline. I think there should be AI in the multiplayer world but distinguishable from real people.
