@nev @mhoye yeah it's a great idea in spirit but in practice it simply wouldn't work the way you'd expect it to.

I did absolutely love closed systems where it was possible. For example you could export a SimCity 2000 city and play in it in SimCopter and Streets of Sim City.

And it would be really cool to have an option to say, render a city you built in a game into a 2D map you could use for a TTRPG campaign or something
