5. El Shaddai: Ascension of the Metatron
While El Shaddai only won two awards following its 2011 release by UTV Ignition Entertainment, it made waves in the gaming community for its unfinished-style graphics, beautiful landscapes, phenomenal voice acting, and both 2D and 3D gaming and platforming mechanics.
Why it would make a terrible film: Inconsistencies of biblical proportions. El Shaddai follows Enoch who, according to some religious texts, was a man who rose to the status of an angel, called the Metatron. In the game, Enoch the man is sent back to Earth to deal with rogue angels who have given forbidden knowledge to humans, established themselves as gods, begotten half-human and half-angel children called nephilum, and in general disobeyed everything they were meant to do on earth. If Enoch fails, God intends to flood the earth (aka, the Noah's Ark story) in order to cleanse it. Anyone who knows anything about Christianity knows that the Bible says this flood takes place. But if you beat the game, it doesn't. This, along with a few character inconsistencies will cause serious waves in the devout Christian community. While that doesn't necessarily matter for everyone, and shouldn't because it's a film, it might matter enough for screenwriters to change the game story's ending to appeal more to the religious crowd. It all depends on who writes the film.
