So, I've come across an interesting Japan-made RPG system that's been translated called Tenra Bansho Zero. Base premise is it's another planet, magic's real, and there's a mixup of feudal Japan stuff (Samurai, Ninja, Buddhist monks, Shinto priests, etc.) and steampunk super-tech(mechs, artificial humans, people with steampunk cybernetics). This would be my first time GMing, so bear with me.
