Since the game is set to be released in like 2 weeks, this seems a bit pointless, but you can head over to Gamespy to submit any question you want about the Fallout 3 expansion Operation: Anchorage. From the Bethblog:
With less than two weeks until Operation: Anchorage drops, GameSpy is preparing an interview regarding the new content. Rather than asking us their questions, they want fans to submit the questions.
If you’ve got a question relating to Operation: Anchorage, feel free to submit it to GameSpy.
