More than any other modern Fallout episode, this one revels in the sci-fi and 1950s fantasia. The tone of the add-on is evident right from the start, when you're summoned to a desolate drive-in for a midnight show. Such an approach is fine, but it's not the only way to expand an open world role-playing game, and Old World Blues takes a different tack. Each gave you a small pocket universe within the larger Fallout world, then led you through it with quests that revolved around meeting - or defying - the expectations of others.
The previous New Vegas add-ons, Dead Money's casino heist and Honest Hearts' frontier myth, were both relatively straight-faced and narrative-driven experiences at least partly defined by their setting.
So here's the good news: Old World Blues brings funny back.
There are certainly moments of levity in Fallout 3 and New Vegas, but the endearingly surreal streak of humour that once made the series stand out has been notably absent since Bethesda took it over.
