I'm playing with a metaphor in which atoms are elements of the game that are pure, aspirational forms. They are the themes and values that I seek to manifest through the game design. Atoms do not explain how things work together. How any of this turns into a real game. Molecules are more coherent game play elements, think rules, algorithms, maybe models. I think the cells category will include how these ideas are actually playable in Evennia. This will refer to Evennia concepts, but not actual code. In organisms we will finally provide the pseudo code recipes and plans to begin coding. Bodies? I'm not sure what that will be yet. It might be design ideas at a meta-game, administration, player conduct rules etc. Finally I might add a category called Gaia.
