While I enjoyed my time I really struggling to find what I feel like I would different on a new playthrough making me worried about longevity of this game.
It really feels like unless bethesda (unlikely) or moders could do something drastic I would not return. Just pick the game back up and do the new thing.
Feels not enough to do by only stick to space. Not enough ammo to not use a variety of weapon. Nor that much other ways to deal with combat that it would warrant a new play through.
