Personal thoughts - being about 15 hours in; the exploration part is far from exciting, the gunplay is not much improved since Fallout 4, the crafting systems have not really evolved at all, the outpost construction system feels very disconnected from any other gameplay - being a completely optional resource sink more than anything else, the ship construction system is clunky as anything and has a bunch of drawbacks to it, the usability of the UI is mediocre at best - probably slightly worse than the original Skyrim UI, the economy seems completely broken - you're very obviously meant to have 2-3 digits fewer in your credits than what the game awards you for regular play even without heavy looting, the characters are rather weakly written and seem strangely delayed in reactions to the story, your chosen backstory never has an actual role in gameplay - only been able to skip two 1k credit payments and a "put the cube in the cube hole" puzzle with it so far, etc.
It's very much a Bethesda game. I'm definitely going to finish the main story - and probably poke into a bunch of the side content as well, but this is definitely not looking like a game I'll have more than a single playthrough in.

I actually ended up bringing out a USB dancepad I've got laying about to play with, since I had to do a bunch of on-planet stuff, and standing and drinking tea while waiting through the traversal for those missions felt much nicer.
