In Unendliche Geschichte, you set out on an adventurous quest to search the world of the "Never Ending Story" to find the "Key of Joy". Each player represents one of the four elements. When your comes around, you get to be a hero.
Most of the game sets you out on solo adventures, but the cards you use make things difficult to do without the help of others. Follow the adventures on the cards (based on where you are on the map) to collect Signposts. When you get three Signposts you can jump to where you need to go (to collect Crystals and Landscapes).
Each player is constrained by their die roll to see what abilities they can use such as intelligence, creativity, skill, throwing, courage and strength, but you may make choices based on what you are given.
