From Wikipedia:
Bible Buffet is a video game released for the Nintendo Entertainment System in 1993 by Wisdom Tree, a company which specialised in Christian-themed video games. . . Despite being called Bible Buffet, the game has no internal technical references to the Bible, Christianity, or religion in general. . . Its game engine was later used in the Wisdom Tree’s Spiritual Warfare. The object of the game is to get rid of the food that tries to kill you. . .The game also includes a quiz section where players answer three True/False questions in order to advance. These questions would be the only Bible references in the entire game but they are only found in the game’s instruction manual.

Spiritual Warfare . . . developed by Color Dreams and released through its Wisdom Tree label in 1992. . . is a religious-themed game heavily influenced by The Legend of Zelda. The engine it uses was also used in Bible Buffet. The player controls a young Christian whose town has been infested with demons apparently under the command of Satan himself. His task is to purify and convert the denizens to Christianity. Strewn about the town are the Fruit of the Spirit, taken from Galatians 5:22-23 and represented allegorically by five fruits (pears, pomegranates, apples, grapes and bananas). The player may use these to defeat enemies by hurling the fruits at unbelievers who repent immediately upon contact. In order to free the town of the influences of “ultimate source of evil,” the Christian must collect each of the six pieces of the Armor of God, which are guarded by “bosses” that are particularly resistant to conversion.

You can play both games: Bible Buffet here, and Spiritual Warfare here.

I love this type of stuff. . .
