Eeeeh, that's a good question. xbox backwards compatibility is software based, so someone at Microsoft/xbox had to make game-specific updates for every xbox title that was to be available on the 360. I don't think Fallout was well received or popular enough to get one of these updates. If you find it used for 2 bucks in a bargain bin somewhere it couldn't hurt to try it out though.
