After launch, Bethesda will make their assets available for players to obtain to make the game easier to mod, and the modding communities of Fallout games are some of the most creative individuals who can add many more stories, weapons, and NPCs into Bethesda games while also breathing new life into games years after release.
While Fallout 4 offers players hours upon hours of fun in both the vanilla game and DLC, a unique feature of Bethesda games is how readily mod-able they make their games to be. Bethesda's Fallout 4 is an expansive open-world game filled with hundreds of hours of content in the base game alone all set in a beautiful but desolate wasteland.
