Bethesda said that it is working with Microsoft to try and increase mod limits on Xbox One. Skyrim Remastered and Fallout 4 mods work differently on PS4 to Xbox One and PC, as players are unable to use external assets.
Modders are currently limited to 2GB of data on Xbox One versions of Fallout 4. The same limits are believed to apply to Skyrim Remastered.
Bethesda’s Pete Hines said that the company was committed to working with Microsoft to increase sizes, but no agreement had been reached.
