I doubt we need to worry about that. I don't see Bethesda jumping off the mod wagon considering how how much it's added to the popularity of their games.
Why would that change?
It didn't throughout their time on xbox….you can mode skyrim and fallout 4 no issue.
I admittedly don’t know much about gamepass but I know window store didn’t allow you to mod games.
I should be more clear though. I don’t expect mods wouldn’t be possible but that they would use Microsoft’s infrastructure to further their attempts to monetize them. Which for someone like me who builds games with 100’s of mods would be a buzzkill.
I don’t lose sleep over it or anything. but it is something I wonder about.
