Fallout 4, the most recent mainline game in the series given that Fallout 5 has yet to be announced, provides players with around 27 hours' worth of content if they only explore the main storyline of the Commonwealth. This makes it comparable to the playtimes of Fallout 3 and New Vegas. In terms of extras, though, Fallout 4 has more to offer than just about any other game in the franchise.
