This as in end-game thing would cost 2500-3000 essence to rename a star system. I would make the game be more of a sandbox.
Why would it require Essence? Bookmarking already allows players to name planets, so simply bookmarking systems could be added to do the same thing.
I wish they'd just make it an admin command (so it's not abused on servers). There are some really great systems with really terrible names. Bookmarking does not prevent you from having to see a star named "Buttfart."
