That's my concern - what do you do? In the above trailer for the latest update with creature riding etc, what are the motivations to go anywhere and do anything?
you can start farming - make money from it - buy ships/fleet while going to the centre of galaxy where you can claim one of systems and/or have fun building your home base or just relax in your space exploration fantasy. But yeah it's a bit tiring and I suspect that it aims at people with OCD.
In preparation for the new update I documented my home base near the centre, just in case it gets wiped out.
