If you want to play the Fallout London mod use this version of the game. Way easier to install on this than downgrading the steam version.
I bought Fallout 4 on GoG just to play this mod and it was worth every penny. This is the best Fallout we got since New Vegas. Quests with choices, skill checks, intresting NPCs and stories, and has no reused factions! Yes, while it's true the games crashes and there's no environmental storytelling, but the devs are working on these issues and everything else, the story, the new perks and traits, the art, everything is just right and they're finally on the 64 bit engine.
