But a good flightsim is more than just a visual engine to create a world. It is physics, avionics, functionality.
I concur. But, oh baby, I do love the eye candy so!
So let me see if I understand this Outerra: Is it meant to be a program for world rendering that would then somehow be integrated or "overlayered" (a word I just made up to show that I have no clue how these things work) with a flight sim program? In other words, Outerra handles the world, and a some other program provides the aircraft rendering/aeronautics, etc.? So you could/would (at least in theory) run Outerra in conjunction with a next gen sim, say, FS-XII or Il-4?
I don't care if I'm completely wrong. I just want my imagination to be happy.
