Nice idea. Real orbital physics would give the gameplay a layer of authenticity that most sims ignore. You’d have to crank out a full n‑body solver, keep it fast enough for many players, and then design combat that feels balanced when you’re orbiting, flying between Lagrange points, or launching an engine burn. It’s a huge engineering problem, but if you can pull it off the result would feel like you’re actually steering a vessel in space. The challenge is making the math accessible to players who aren’t astrophysicists. Probably start with a simplified two‑body approximation and then add perturbations. Keep it modular, so you can swap out physics engines as you iterate. In short, the concept is solid, the execution will be the test. Good luck.
