Mythtaken

Mythtaken is a rules-light storytelling game designed to create stories in the mold of folklore and legends. It has few requirements other than a medium through which the players can communicate and share notes—you can easily play it in person, or through a messaging app. It's designed for 3-6 players, and intended to spark fun sessions of collaborative storytelling, brainstorming, and joking around with friends.
