For me, the mods keep the game from becoming too punishing. FNV needs a lot of mods to keep the bugs and the invisible walls from killing your game. FO3 and FO4 need quest fixes and additional quest mods to keep them interesting.
Bethesda games are always boring trash. The real game won't even appear for another year or two at least (after the modders have finished fixing all the bugs, the horrible writing, the design flaws).
They "apologize" about "confusion" and "angst" that us stupid peasants have? That doesn't sound very apologetic to me. That sounds like they're doubling down.
You can land on Pluto though you aren't really meant to. It's just there for decoration.
This is similar to how you can glitch outside of Whiterun in Skyrim, though doing that in the same worldspace as Whiterun will just let you be up close to the low-detail versions of the outer world, which you aren't really meant to do.
