I don't think you caught the point. Its most likely in-game photage, not some pre-rendered scene.
It probably shows off the capability of the UE4 engine so the end result wont be much different from the actual screenshots.
What worries me is that they are looking for investors, which means they don't have confidence in their vision or current resources. Crowd funding is a really strange creature.
I did, but I don't think you caught mine.
I doubt that is what the live game terrain will look like. If they are releasing in Fall, they should be in Beta.
They should be able to post live multi-player actual game-play videos of planes flying through that terrain.
Real time game play, not some pre-rendered cinematic scene.
If they had video like that, on that terrain looking like that, I'd think they'd be posting it.
Because surely they wouldn't expect anyone to believe empty, static, concept art pictures.
