They might go up but I’d be surprised it will rival Skyrim. I’m a Skyrim fan, yet I’m not enticed to play Starfield for reasons beyond me. It feels like it’s lacking something and I can’t put my finger on it. I don’t believe mods would make much of a difference, but who knows, maybe I’m wrong.
I modded Skyrim (and Oblivion) because the vanilla game was exciting already, in spite of its flaws. I couldn’t be bothered otherwise.
