My plan for this wasn't much more complicated than this, though I put a list of things I'd like to do with it in my latest update dev log.
At one point I did have the idea for an elaborate action RPG resembling a cross between Daggerfall and Minecraft with elements of shooters (Hexen) and even The Sims (with NPCs) -- but I'm sure all that is way beyond what I can realistically do. Anyway, this is not planned to become that!
