There exists a light novel series called Overgeared. The protagonist and the plot are interesting but irrelevant to the point. The setting is a VR game world with an unpredictable and independent storyline which is made by a singular supercomputer AI. It seeded all NPC AI and predicted plot lines and gave both NPC's and PC's quests to challenge them. But it was curious that both play an almost equal role in the progression of the game plot.
I'm not expecting anything even remotely close from SBS in terms of AI. But at what point are we going to hear more concrete information about the roles of NPCs, their mechanics and the extent of the influence we have on each other?
