I say that it's become a kata because it's a little project that I maintained in order to understand how games work and how people and games interact. It's never been intended as a complex or rich RPG. Rather, it's the kind of exercise one engages in in order to perfect a single technique. Those techniques can be used at a later stage to produce something more complex and interesting, but that's a larger work which requires the basic technical components to be mastered first.
So, the little kata that I call Nobles will be ready and available soon for your tabletop gaming enjoyment.
