And to be fair - you do not need the bestest of the best FSDs on every ship in your fleet. I plan on outfitting ~10 or so of my ships with it, primarily my combat ships (which have no extra slots available for things like FSD boosters and are weighed down with armour so every extra ly helps on those) and exploration vessels. For the average bubble runabout, the extra couple of ly range is fairly irrelevant, since most journeys are 2-3 jumps at most.They're rare. Each one unlocks a whole glittering FSD. While you're looking for them there are other things to collect too and the scenery is spectacular. When I play a game I don't wish for it to be over quickly.
