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
I don't think Microsoft would allow it. They so badly need a win without reservations when it comes to releasing a big game. We'll see though.
Never underestimate M$' ability to release terrible products because they deputized a single boomer product manager to do whatever seemed cool to them.
