Many fans would argue that Fallout: New Vegas is the best in the series. Released in 2010, the game has aged considerably in the intervening years. The fact that gamers keep coming back to it, again and again, is a testament to its superb overall quality. The RPG mechanics are one-of-a-kind, with the game combining the best of both the old-school Fallout games along with modern innovations to make for a brilliant role-playing experience that continues to be Obsidian Entertainment's magnum opus to this day.
