Hot off the heels of Fallout 3, Bethesda contracted Obsidian Entertainment to make Fallout: New Vegas. Fallout: New Vegas critical reception at the time was a bit less than Fallout 3's, but the game has enjoyed increased popularity in hindsight, with many fans calling for a sequel. No Fallout: New Vegas sequel has been announced at the time of this writing, but a reputable insider claims that early talks have started.
