クリスタルと商人 (Crystals and Merchants)

A storytelling based game wherein an adventurer attempts to sell items to a merchant. The adventurer comes up with a backstory for the item, then the merchant must add onto it while attempting to bargain the price down. If a player fails to come up with something to add onto the story or notices a contradiction in the opponent's story, the game is over and the prevailing side wins.
