Well they did - about 25-odd years ago, and it was called Frontier: Elite II
And it was very popular.
And some people got gud at the Newtonian flight model.
And the others just blamed the flight model.
And I just noticed your avatar and it made me smile

It was easy to get gud with the FE2 flight model. It was not very hard.
They main problem was that it didn't matter in combat if you flew good. Only aiming was relevant. Aiming was extremely easy with ultra fast pitch and yaw.
Your oponents were usually dead while still a pixel big.
