Crave is a social psychology game, with only verbal components. Crave is played by creating the need of some tangible object in another Crave-player's mind, enough so that they physically leave the current room and travel to some destination to obtain said object. They cannot be tasked with retrieval and cannot be forced to go. The idea is that you can talk so glowingly, so descriptively, so persuasively about some item (food, beverage, clothing, knick-knack, etc) that it would induce someone else to go get it. Get someone to do this, and you won "a Crave".
