General Interplanetary drive.

Frontier: Elite II and Frontier: First Encounters games.

Those were regular reaction drives, not superluminal or space-warping in any way like the FSD. Point at planet and thrust for a week or so. It didn't take that long for the player, since it was a single-player game and you could speed up the simulation which you can't do in multiplayer for obvious reasons.

Basically they were FA-off engines without an arbitrary speed limit.

Sure, but there is a significant difference between the way the interstellar FSD works and the supercruise FSD. It's not hard to imagine a drive system which can do supercruise but not interstellar travel.
