New Vegas is an oddity in that it was published by Bethesda but the game itself was developed by Obsidian Entertainment. Fallout: New Vegas is probably more of a direct sequel to Fallout 2 than Fallout 3 was.Īllow me to explain without spoiling the plots of both the first two pre-Bethesda games The originals were set in a nuclear devastated California whereas 3 and 4 are set on the east coast of war-torn America.
