From itch.io: You are a World Walker. Whether through experimental technology, forbidden arcane ritual, god-curse, or sheer force of will, you are able to move between worlds. It is not easy - there are dangerous worlds out there, and you can get lost. But there are great wonders to see, limitless possibilities to explore. OTHER WORLDS is a small system for building and travelling among worlds / dimensions / multiverses / planes. Create worlds on blank cards, share them, shuffle them, and explore. What will you find out there? Will you ever see home again? Do you even want to?
