[6] Godville is a similar game that took inspiration from Progress Quest.

[11] In computer games, the term refers to programs that use artificial intelligence rather than human players,[12] for example some fighting and real-time strategy games can be put into zero-player mode where multiple AIs can play against each other.
Humans may have a challenge in designing the AI and giving it sufficient skill to play the game well, but the actual evolution of the game has no human intervention.
