The Galatian Academy quest chain is an incredibly long (took me 5 hours?), mostly linear chain of mostly fetch quests. The first time around it's quite fun because of all the reading to do, but I can't imagine anyone being happy to do it twice. Its existence severely limits the replayability the game has, and Starsector has been known to be a highly replayable game so far. The chain can hardly be ignored either, because of how improtant the rewards are. (Cue people commenting about how you can find the alpha site without the quest as if it's not a 1 in a 1.000.000 random chance).
Proposed solution: split the chain into multiple independent shorter chains. Neutrino detector, Transverse Jumping, Alpha Site, At the Gates. Maybe lock some of them behind player level requirements so people don't rush them.
On a somewhat related note, it's really lame that quests that award abilities have no special reward if you already know the ability from a skill. Would be nice to have upgraded versions for people with both. (Transverse Jump can charge faster, Neutrino Detector can no longer give false readings).
