While in theory it seems like a good idea to use established book fiction as a setting for a computer role playing game, but in practice it seems as likely such a game will be 'good' as it is likely a game based off a movie will be 'good.'

Some of this probably has to do with the somewhat impossible task of re-creating a universe as it might exist in the minds of hundreds of thousands, or millions even, of readers. Perhaps such efforts are futile from the start.
