Fallout: New Vegas
Fallout 3 took the massive step of moving the Fallout series into a fully-realized 3D world, but New Vegas featured the return of some of the Black Isle Studios writers who helped create the original two titles. Beginning with the hero, known as the Courier, being double-crossed in the Nevada desert, New Vegas features several factions (of varying degrees of evil) and tons of content, much of which requires more than one playthrough to discover. New Vegas also added a hardcore mode that requires the Courier to take into account dehydration, hunger, and ammunition weight.
