I can't believe I'm saying this but I liked the demo for ground of aces. Even despite all the modern game cliché amount of browns in the RAF.
It was a bit as if someone made a rimworld mod with most features cut out and narrowing the game down on a few core aspects.
Way more streamlined with less actual options but as a consequence it is also substantially focused on it's one trick.
With a big part also being that the points generated by your planes flying successful missions is the only way to get more crewmembers/ replace the dead ones.

The lack of a tutorial did hurt it though. Sand pits for example are a source of sand if you destroy them but you can also harvest them which doesn't remove he pit itself.
