The short answer is yes, and that's because Fallout: New Vegas is one of those games that have aged incredibly well. It's a decade-old now, and when looking at other titles that are new on Game Pass (like the Dishonored franchise), it's worth wondering if newcomers or veterans should play New Vegas on Game Pass, especially in 2021. The title was notoriously bug-ridden at launch, but as the game releases patches and DLC, it became a classic well in its own time. Among these new games is Fallout: New Vegas, a classic entry in the franchise which was primarily developed by Obsidian Entertainment, not Bethesda. There's a lot that, if players haven't touched before, is well worth trying out now.
With the flood of Bethesda games on Game Pass, it's easy enough to fill overwhelmed.
