Recreation.
WHERE IT IS USEFUL
Explaining rules Explaining strategy Generating puzzles and quiz questions Creating material for games you run
FOR EXPLAINING RULES
"Explain how [game] works to someone who has never played."
Useful, and verify against the actual rulebook. Generated rules contain errors.
FOR STRATEGY
Explanation of principles is generally reliable.
Specific claims about optimal play may not be.
FOR RUNNING GAMES
Generating scenarios, characters, descriptions and quiz questions.
A genuinely popular and low-risk use.
FOR PUZZLES
Generated puzzles frequently have errors or multiple solutions.
Check before giving them to someone.
FOR PLAYING AGAINST IT
Language models play most games poorly, including ones they can describe well.
That is a useful illustration of the difference between describing and doing.
WHAT NOT TO EXPECT
Reliable arithmetic in scoring Consistent rule application
THE PRACTICAL USE
Preparation and explanation, not play.
