Yeah, same. Epic's Matrix demo implemented it and even without a plot, the interactions were so heavily guided that the distinction was pointless. So you can find out what that NPCs spous's name is and their favorite color. It's that neat? Sure it's neat. It's it going to make it a better game? Probably less than hiring another good writer to make NPC dialog. To be truly useful, I think they would have to be able to affect the world in meaningful ways that worked with the game plot, and again, when you clamp that down as much as you'd need to to still have a plot, you're looking at a fancy decision tree.
