  The understanding and acceptance of evolution by natural selection has become
a difficult issue in many parts of the world, particularly the United States of
America. The use of games to improve intuition about evolution via natural
selection is promising but can be challenging. We propose the use of
modifications to commercial games using artificial life techniques to 'stealth
teach' about evolution via natural selection, provide a proof-of-concept mod of
the game Stardew Valley, and report on its initial reception.
