I might be inclined to agree with you, if it wasnt for the absolutely atrocious amount of loading screens.
Its definitely a game where it feels like they put all their dev team effort into the first parts of the game, on the assumption that you’d be hooked enough to ignore all the rest of the bullshit, poor decisions, and bad mechanics that come later.
I think making anything of Starfield, for modders, would be such a monumentally huge task… That they could probably just do it in skyrim/fallout 4 with just a portion of the effort/stress/hassle.
