I'm 13 days (312hrs) in @ lvl 106 (no mods)
I didn't quite make NG+ 10. Didn't get bored but I found an NG+ universe I liked and have been exploring and outpost building this one.
All of my last 6 days game time have been outpost building, ship capturing and ship building plus the occasional quest. The building elements alone are for me enough of a game to be really enjoyable.
I decided to become a weapons dealer in this universe. When the outpost weapon case spawn weapons function worked, I spawned in loads, built a great base with loads of displays and crates and have been trading in them ever since.
I won't move on to a new NG+ now until I have 100% achievements and I can then mod the game to build what I want and spawn weapons etc.
My first play through on Skyrim lasted 80-100 ish hours before I parked it for a couple of years so this has given me a significantly better run.
Once the Skyrim expansions released and mods evolved, I was interested again but only when I could mod my character to eliminate the levelling grind etc.
@Aegis I think fewer of us are enjoying Starfield long term but that's no different to previous Bethesda releases or other RPGs like Baldur's Gate; a handful of hardcore enthusiasts used to be sufficient for single player RPGs to measure success.
It's just expectations and opinions are so much more polarised in this season compared to when for example Skyrim launched. Plus everyone expects everything perfect from day 1 now. Skyrim took 5 years to release a version of the game and mods that I consider gave it unrivalled status.
@ the others, the game could be hugely improved and there is lots to critique, for those of us who find enough content to make it enjoyable, these don't detract.
