The Fallout series is iconic, storied, and means a lot to a lot of people. The team at Bethesda, thus far, has seemed cautious about the liberties it takes with the series' basic elements but more than willing to stick to its guns in regards to bringing it to the modern age. The game's big reveal went down almost a year ago -- more than long enough to assuage the misgivings of (sober) would-be critics.
Gamespy know Bethesda is probably on the right track. They just want to play it already, especially after a recent visit in which the developer showed off a few scattered bits and pieces of Fallout 3.
