A lot of people seem to believe that Outerra is going to be the next great thing in the FS arsenal, while to others it is simply a procedural world generator that happens to include a flight mode to show off the created world, but it will never be a viable ‘hard core’ flight simulation.
Whichever camp you find yourself in, or even if you’ve never heard of it before, there’s no denying that the application is showing off what procedural terrain generation is capable of and there is, equally unquestionably, a flight simulation element to it as it features both air and ground vehicle physics engines.
To show both the engine and its capabilities off, a Technology Demonstation can now be downloaded from the Outerra website (link under the left hand sidebar entries) so you can see what the engine is currently capable of.
With the technology and engine developing and improving all the time, it’s certainly one to keep a close eye on, still.
