King James Bible, a unique entry for the Game Boy released in the USA, offered a digital version of the King James Bible. It is unlikely to have featured traditional game elements but may have been a simple text-based application allowing users to read and navigate the biblical text.  The intent was likely educational or religious rather than entertainment.  Its unusual nature makes it a particularly interesting title within the Game Boy library.
