Bethesda is now owned by Microsoft meaning Starfield will be on gamepass day 1. Gamepass already heavily restricts how you mod your games with protected folder bullshit at the OS level.
I have a feeling that it'll be really hard to use nexus with Starfield if not entirely impossible as Beth and Msoft will want to kite you through their new mod store where they take a sizeable chunk from mod makers
Mods have always been Bethesda's saving grace so they don't have to worry about the game being more than half functional at release. Projekt Red would have received a lot less backlash if they had released a creation kit with Cyberpunk so fans could fill in all of the gaping holes.
