That's not the only issue either. People who play on consoles? No mods for them either.
The newest (Xbox PS) consoles have mods. The PS5 is very strict though; however, the mods they allow can’t have new assets (must use in game assets and no script mods) so theirs may actually survive in the long term. Xbox is a mixed bag though some will survive in the long term while others won’t. I can see new NPCs added, but they will be “dead” like the vast majority of NPCs on the Nexus. Well dead unless your goal is s..lab….(PC)… Even those mods fail in updates, so the basic repurposed assets to assemble an additional follower and additional slots is possible if all you have to change a setting in the directory. PS5 may even block that… not sure.
