I know it's inefficient and stupid, but perhaps someone could make a flight mode mod that made ships with sufficient directional momentum degradation abilities able to fly like tie fighters. Basically, what I mean is that in space, Newtons laws apply; however in sci fi movies, ships fly like they're on rails. Essentially if there was a mod that included inertial dampening AI which would activate directional RCS to make spaceships fly like airplanes, it would make unlimited fuel fake futuristic space fighters/frigates more fun, and more interesting to look at for machinimas and whatever other cinematic space fighter scenes (mostly) people would be using this for. (TL;DR, Space Engineer's inertial dampeners in a mod so that RCS can make ships fly like planes in space. They would still use RCS, just in an inefficient yet pretty manner.)
