This would by my brother, Robert’s, “Quest For The Dice Of Destiny.” We did not finish it, but we did have a lot of fun up to that point. Prior to that it was someone made a dungeon and those that didn’t make a dungeon bought modules.
There was a lot of build up as to what we would do, but the game stalled and we never got it going again. We were having fun with it. As I recall, Robert got bored with it and dreamed up something else.
It would be best described as a complete world with ecology, weather, calendar, places, plots, NPCs and lots of ideas with lots of materials to back it up. There are lots of places we have never explored, and only one character has ever gone off the map. The area is about the size of France and Germany. It also has a sandbox quality as Robert has planned out enough of it that he does not have to make it all up as he goes along, but he is creative enough and go with the flow enough to make it all up as he goes along. I have a hard time telling when he is making it up as he goes and when he is going off planned information he has in his head.
I can sort of do that with the campaign I developed for my sons. It surprised me how ideas just came to me to fill in the gaps and make things happen. I still find it a challenge to scale things to be appropriate for low level characters, but we are having fun with it.
