Do you mean they created their own fictional geographic worlds (or parts of worlds)? That's amazing. Many - including Tolkien, I think - have started that way. Sometimes, the world finds out about it. Robert Louis Stevenson started with a map.
Hah, I should have been more specific. They created programming environments that are entirely their own. Although Jon has created several games which include fictional geographic worlds.
