Edit: ugh, I lost myself in this reply. It's just geeking about the future what could be possible, mostly not worth reading if you value your time.

This is one of the most exciting developments to me, the actual AI of bots or NPCs. Not only for RPG games, I can also envision multiplayer games to be more fun playing offline with bots. Imagine they act like humans, with their hearings and trying to trick you out in Mario Kart, Street Fighter and Counter Strike. Obviously we are long way from this, but this is very exciting to me.

Also GTA where people act normal and do stuff humans would probably try too is exciting as well. In RPGs imagine you hear about a hero in a village who defends its town and you recruit him, finding out its just a normal NPC for other players, but got strong because it found a holy weapon you dropped near to him in the beginning of the game. Just totally wild idea I know, but what if the future of games (probably 50 years from now... sheesh) is extremely rich and dynamic? I have no idea how this vision could be accomplished without AI and always server connection to power servers...
