'Inertialess' systems like stutterwarps and so on are one way. They at least keep the
required real velocity change for a ship down to the relative veocities of the stars and
planets the ships are to visit. If you're playing a game where concerns about breaking
physical as we understand them is a problem they are likely to be off the list, of course.
