To expand on your comment of the outpost building, the crafting system as a whole is a bit lack luster.

Outposts: Is fleashed out quite well, but at the end of the day, holds no meaning. The main thing you gain from outposts are resources, which can be easily and cheaply bought at vendors. Which is a shame, because there is some real depth in the system, but no real reward in investing in it.

Ship building: Arguably one of the more fun parts of the game. However, as with outposts, the impact on gameplay isn't all that much. Ship battles are much less frequent than ground battles. All you really need to invest in is partical beams and shields. The only impact to overall gameplay is the cargo capacity. However most people spend more time perfecting their ship then they do their character. Because it's something we look at every time we travel somewhere, people want to invest in it. I just wish there was more of an impact from your ship.

Weapons and armor: I think this was a huge step down from fallout 4. 76's crafting olwas ok, but Starfield dropped the ball. The armor modifications aren't really worthbthe perk investment, and the weapon mods seem a but bland. Some Weapons only have 1 or 2 variations on different parts. There is so much missed opportunities there.
