Follow is a game where you sit down with your friends and play characters working together to achieve a common goal: your quest.
The quest you pick decides the kind of game you'll play. You could start a rebellion, cure a disease, slay a dragon (or a cat), or get your candidate elected. If it's something people can work together to accomplish, it could be a quest.
Will your characters stay united or will their differences tear them apart? Will they triumph or will their hopes go up in flames?
