I saw a thing from the creators once that said the thing that is most likely to keep players from finishing the game is failing to find one of the major secret locations in the first like 5-ish hours. They explore and find a bunch of information and places but don't manage to have a break through quickly enough to have that moment that gets you really hooked. In fact so many players quit with being so close to that moment. And the players that have that moment are many time more likely to end up finishing the entire game.

Unfortunately, sounds like you fell into that camp. Only thing I can recommend, if you are interested, is come back at it with fresh eyes, read through the ship log again (everything listed there is significant in some way, none of it is a waste), poke at what makes your curious, maybe ask for a specific hint of you end up needing, and get that first big "Aha!" moment. See if you're not hooked then.
