its all fun and games until the server decides that you are a threat and sends the NPCs on you.
Seriously though, the concept is neat, essentially centralizing the AI system to give NPCs virtual awareness of the world, the thing that jumped to my mind as i read this is how modern navigational apps track low traffic and accidents and reroutes the driver to the fastest option before entering the low traffic road, which would be doable with an AI system like this.
With that said, i am not sure of its worth. Rockstar already got excellent AI system compared to everyone else on the market and the uses sound pretty limited for added functionality.
