Probably blashpemous to Christians
I would really love to, some day, make an epic video game that draws from the cool parts of Catholic lore (think Dante's Inferno and celestial wars) and where the ultimate twist is (spoiler alert for a game that will probably never get made...) that the "Satan" of this world is the original God, cast down to Hell and driven insane when Lucifer led his successful rebellion and assumed the throne of God for himself.
