I wrote up a very light PbtA game about mischievous animals trying to act like people and generally committing low stakes crimes in the process. The fever dream prototype of this game turned out to be the perfect fit for the roleplaying club I ran for elementary schoolers last year.
YOU ARE A STARFIGHTER. You dance through the void, strapped into a fragile hypervelocity shell capable of glassing moons. Now your colony worlds burn. Your fleets are scattered. The false prophets and traitor kings call you renegade. They hound you through uncharted space while billions of ghosts cry out for vengeance. Let them come. Show them how easily the hunter can become the prey.
