The world is underwater. It wasn’t always, but has been for as long as you’ve been alive.
You have a raft, bound together from floating pieces of debris, where you have lived most of your life. It has a sail and a rudder. You can usually distill enough fresh water and get enough food. But you know life could be more, may be better elsewhere. And perhaps you will sail there.
This game is for 1-4 players and takes about a half hour to play.
