Huge fan of science since I was a kid, picked up this game a few months ago and have been enjoying it for many hours. The game engine is a shame though, especially on the physics performance side, severe lack of optimization. Also memory management is just sad, this game takes more memory to run than GTA V, which is a 60GB game. Other than that, the concept of this game is definitely one of the best. Also the mods, loving the mods, especially FAR, adds so much more depth in designing planes.
