I am Nathan with an innovative idea to create a game for christians to play which links to their reality.
How? every problem, situation and sin, a modern day christian goes through will be interlinked as much as possible in the game. For example when ever their character on the game does something wrong a demon will pop up and based on what the christian says and how much fire power spiritually they have will determine if that demon goes away or not. Also how much scripture they know to counteract an attack from a demon and even people on the game that are on the devils side.
Fasting to gain strength, temptations of food, women alcohol and partying should be part of the temptations just as in reality of a christian. Easy, Medium and Hard should be an option in the game so their character can build faith etc. Should be linked to voice so the christian playing can pray or say things to attack evil spirits on the game. If they get beat by a demon in a battle options will come up suggesting what they should do in terms of winning.
