The challenges and quests were developed to keep players occupied while playing through the story. Molyeux told Leach about the ways of good and evil and the system's reflection of the player's behaviour, and provided him with a digital copy of the Bible with instructions to study the concepts due to their connection with gods and men. Leach decided to supplement the idea of evil with mischief, as he thought being completely evil by annoying or killing followers was senseless. Molyneux wanted a conflict between good and evil, and for the enemy gods to have the opposite alignment to the player. As a method of introducing the player to miracles and combat, a god whose alignment is the same as the player's was added.
