It looks like the success of Fallout 3 has prevented us from having to endure a massive hiatus between getting a new entry in the series, as Bethesda has just announced an all new Fallout game dubbed Fallout: New Vegas. Notice that there is no digit attached to that name, and that's because this is not a sequel to Fallout 3, but rather a distinct and separate entry. From the horse's mouth:
"It is not a sequel to Fallout 3," Pete Hines, Head of Bethesda's Public Relations said. "It's simply another Fallout game in that universe." Hines added that the game will play out similarly to Fallout 3, stating that it will be very close to the experience of Fallout 3. Additionally, because the game is taking place in, what we assume Hines meant the Fallout 3 universe, we should be playing a story that unfolds elsewhere in the United States (Las Vegas, clearly), as opposed to Washington D.C.
The game is set for release on the PlayStation 3, Xbox 360, and PC next year in 2010, with developers Obsidian at the helm. If you need a refresher, Obsidian are the folks behind Sega's upcoming Alpha Protocol, Sega's mysterious Aliens RPG game, and Star Wars: Knights of the Old Republic II. There's certainly a solid history and reputation behind the developer, so expect nothing but great things. Additionally, Pete Hines stated that development of this game will have no affect on Todd Howard's project within Bethesda.
