Wrong thread I know ... but I had some crazy thoughts : for a system that has not been scanned yet (and you don't see the "explored by ..." message on it) then you have to go through some kind of mini-game (think Interdiction but different) when jumping to that star system. Depending upon your skill / drive condition / etc the end result is a jump +/- some distance from the star. It's basically a test of how well you can plot.
Another suggestion would be to not give the alignment indicator when jumping to a new undiscovered system and you have to point where you think the star is (there would perhaps have to be clues and you have to use your navigation map to help - accuracy based upon modules installed / condition of modules / etc) .. the nearer you are to the exact star direction determines how close you jump to it upon arrival , again +/- some random factor. [so think of the system being a bulls eye and concentric circles around it, each band representing +/- 1000ls for example)
(Both suggestions could mean you jump
into a star ... a fate worse than death, but would really add some drama !
