I am not sure if this is where I would post this, but I thought I would give it a shot.
I have a suggestion about campaign settings. I absolutely loved the advanced look into the plains produced in Planescape. All the different maps showing the different places in the plains from the lawful good plane of Celestia to the chaotic evil of the abyss. The different settlements on those planes to the unique environmental challenges of planes like Limbo. Information on notable personalities in each place as well as what plane the different gods call home. The idea of the city of doors made it easy for dms to change the setting easilly and quickly.
I thought I would toss this out there to see if there is an interest and maybe lead to such a production.
