Had a few plot points in the UC quest line that were cool. I liked that zero g casino fight.
Inventory management was shit, but that's pretty common to the creater.
Base building didn't really interest me in Fallout 4, and didn't do much for me here either. The crafting was weird. I don't like using my combat feats to make better sandwiches.
The ship customization was cool, but since you are just jumping to your destination it didn't matter much for my playthrough.
The proc gen planets were predictably empty feeling. I was worried about that after they said they were putting 1000 in. No way they could hand generate enough content to fill that, which was their strength in The Elder Scrolls.
I suspect they got caught up in the No Man's Sky hype and forgot to use their core strengths. Combine this with not enough innovation on their weaknesses and it was mid.
If they would have done an Expanse scale game, set within our solar system, where you had 2 large terrestrial planets, a number of asteroid bases, and kept their scale in check they may have been able to pull it off. But it felt just too stretched out.
