Interplanetary flight in I-War 1 & 2 was done with the inertia-less LDS drive (same as Elite: Dangerous super-cruise), you practically didn't do it in Newtonian mode opposed to the previous Elite sequels where everything was done in a single Newtonian mode, which also featured realistic orbital dynamics, moving celestial bodies and freeform planetary re-entry.
That said Elite: Dangerous regular flight physics are still Newtonian, even more so than I-War series as it features rigid body dynamics and not a point mass, but the ships have very strong maneuvering thrusters a flight control system computer to counteract the skidding and keep it within a certain speed limit, but you can partially turn it off.
EVE is 3rd person roll & dice, point & click RTS style controls, with empire building and almost fully player driven world. It's totally different from Elite.
The sequels were much more extensive and attempted a Milky Way galaxy with realistic 1:1 scale star systems with orbital mechanics and seamless planetary transitions.
The reason Elite TNK was pulled was because someone was selling it without permission.
