Okay, I wrote an RPG about Robots. Well, I wrote 3 of them. I tried to carry them along the lines of GNS, just to see how it would work.
Robot Simulation is the S part. It's the one that most emulates silly robotness, without any lofty story goals or competition.
Robot Battling is the G part. I know that G doesn't always mean player vs. player. This one is basically a cute little fighting game with fortune in the beginning.
Robot Drama is the N. This is where I'm most sketchy on game design. I basically set up a conflict between Robotness and a Robot's Soul, and players are rewarded for scenes that play up this conflict. If the players all enjoyed a scene, a Player can tilt her Robot towards Soullessness or Soulfulness.
Anyhow, three games in one. Whee!!
