Most of the games systems feel incomplete or rushed. After you get through the core planets you will just spend all your time walking around large empty spaces while seeing the exact same procedurally generated stuff over and over again.
Ship building is fun, even though every time you edit your ship every single thing in the ship gets moved to the ships inventory which gets old fast. Iโm not sure why that feature was left in the game, but I could say that about a lot of things in this game.
