There is very little information around about it now but the X-Plane people used to have a hardcore realistic space combat simulator with proper physics.[/quote:0ae33cc9d7]
I’m really trying to find a balance with the flight physics. I did some user tests with full newtonian physics (no drag) and most people found it difficult to pilot, especially in regards to lining up attacks and/or collisions.
So at the moment there is drag in the game for ships, though there is still momentum and it is a physics simulation.
I explain away the drag as an effect from the ship’s singularity power core, everything without a power core (like asteroids) won’t have any drag at all.
