as far i understand no man sky when you find a crash ship it has 2 slots more than the current one you have.
so i suggest for making no man sky last a bit longer that cohh can only upgrade his ship true that system.
he can scan only 2 times on each planet for a crash ship.
that wil give him a good variation of ships.
a time cosuming way to get to his best ship.
a more dificult way since he cant spend credits to buy ship.
a big variation of planets to explore.
sorry for my bad english i hope every body understands it.
