When I started the project, I had created a checklist inside my head, and on paper. I first came up with how I wanted to separate things (books and what not). I wanted to do a core book, with a GM book as well; as such having separate books that touch on things that could be expanded on, or even a book about what happens when you start becoming a god. Then from that, I started making a chapter list for both the core and the GM book so that I know what sort of systems and what not I had to touch on. I had things from the core mechanic, to how I will go about skills and other things.
Now that I have told this story, the next few posts will be about how I decided certain aspects of my system, as well as some tips.
