Fallout 4 has a huge following, but at least it had its own DLCs that extended to the final Nuka-World expansion. This was a grim announcement for PS4 Fallout 4 owners, where mods are typically the lifeblood for those who want to expand on their creativity, share their newly imagined worlds, and extend the life of the core game. During that time, Bethesda explained that they would find another way to achieve player mod utilization for PlayStation 4 owners. The issue back then wasn't a technical one and is more derived from a file-size policy. In September, Bethesda made the announcement that both Fallout 4 and Skyrim PS4 mod support had been blocked by Sony. VG 24/7 seems to have been gauging the size, comparing previous data and other information involving Xbox which is five gigabytes.
Skyrim: Special Edition has a one-gigabyte cap, and Bethesda mentioned in the past that they do plan on bringing up the limit, which was 900 megabytes. The Fallout 4 mod file size for the PS4 and Pro will have a limit. The 1.8 patch was available on PC about a week ago, according to, and patch notes pointed out the updates.
