Fallout: New Vegas is an action role-playing open world video game developed by Obsidian Entertainment, and published by Bethesda Softworks. The game is based in a post-apocalyptic environment in and around Las Vegas, Nevada. It was released for Microsoft Windows, PlayStation 3 and Xbox 360 in October 2010.
Even though it directly succeeds it in order of Fallout game releases and also shares its engine, Fallout: New Vegas is not a direct sequel to Fallout 3, though the game offers a similar action role-playing experience to Fallout 3. The game marks the return of many elements found in previous Fallout titles; many employees of Obsidian Entertainment previously worked for the now-defunct Black Isle Studios on Fallout and Fallout 2.
such a disappointment. Fallout 3 is one of the best games ever. This feels like an overpriced expansion pack void of any real interesting story.
