Altogether, it will take players 125 hours or so just to beat the primary storyline of the entire Fallout series if they play the games back-to-back. There's plenty more to see in the apocalyptic world of the Wasteland, however, and it might be worthwhile for Fallout fans to instead take up a much slower pace as they travel through the many secondary quests the series has to offer, meeting various NPCs and discovering unique landscapes. In that case, it could take up to 265 hours to beat every Fallout game, a mission that players may be willing to undertake in preparation for the eventual announcement of a potential Fallout 5.
