Atomic Monks
Besides the overall concept, one of the first things I did was create a set of customized tools for editing and managing the game. The various utilities were role-based, so I could (and did) farm out some of the work to others. These tools were completely web-based originally. Later I was starting to spend more time fighting against the browser than creating the tools, and switched over to a custom WPF application that used the API I had originally set up for the web version.
You can see below that all the content was created through this utility. This included maps, quests, encounters, conversation trees...everything you need for a proper RPG.
