There was this editor that let you make esm files. I can’t remember if it was already in the game folder or you had to download from steam but it must not have been hard to set up. I remember using it to make one of the buyable houses really big on the inside.
Starfield could have been a way better game if all they did was fuck it up like 45% less. They could have alternatively just delivered on their promises of making the game easy to mod and let the community handle the rest but they fucked that up too. Only the most dedicated of Starfield fan would have the patience to sit down and do all the shit it takes to add a new quest for example. Iirc even Skyrim came with a mod editor with ui that was easy to understand. Right now all we have is a community xedit project that’s somehow even harder to run on Linux than Starfield is.
If Nintendo would put half the effort into game development as they put into picking legal fights, maybe they could make profit off their video games enough they wouldn’t have to do lawsuit trolling.
