I am not allowed to post links or anything, but you can do a search for Christian Role Playing Games, there are a few that come up...
HOLY LANDS:
Holy Lands is THE Christian RPG (role-playing game)! It’s the medieval pen-and-paper adventure game that puts your character against the demons, devils, and sorcerers who want to destroy the medieval church. You must use your character’s prowess, wits, and faith to fight the evil enemies of God and the enemies of the medieval kingdoms.
The Way:
The Way is an educational fantasy role-playing game for church youth groups. It is Christian, but non-denominational, and therefore useful in all mainstream churches. It lets the players deal with complex moral problems and serves as a basis for teaching a Christian way of life.
Hope this gets you started atleast :thumbs_up
