Finished the main quest and all faction quests in Starfield... and TBH I found it all a bit underwhelming, the ending really did creep up on me when I thought I had loads left to do.
There's enough there to warrant playing NG+ but I think I'll wait for a while until Bethesda start to release some extra content for it.
I really did enjoy it, but whereas it's a good game, it should have been an amazing game, let down a bit by inconsistencies, archaic systems such as inventory management and too many fetch quests.
My absolute highlight was the ending of the Crimson Fleet questline - that was epic.
