Procedurally generated stories seems like the next frontier for RPGs. I would like to see something like the later Elder Scrolls, where all the NPCs have routines and personalities, and everytime those interests conflict with eachother, they create a procedurally generated quest. Then that NPC's story continues to progress and the relationship with the player character evolves based on how the player interjects as the stakes continue to get higher and higher. Even wars would build up and play out a different way everytime. Most open world developers strive to create a "living, breathing" world and this seems like the next step for Bethesda's radial AI experiments.
