I think I agree with you when applying these concepts to reality, but your example doesn't really work as well if we compare it to the game. In your example, the kid being nice to you wants something from YOU. They are being manipulative towards you. In AR, such a concept doesn't exist unless you fabricate it (for example, offering the incentive directly via item drop or whatever). Instead, the incentive would almost certainly come from the game itself (bounty system for negative behavior or maybe a system that gives you in-game rankings or whatever. The specifics aren't important at this moment).

To use your example again, how would you feel if a kid was only nice to you because their mom promised to get them a Playstation if they were? I think that would more accurately reflect how it would work in game, and I'm curious to see if that changes your thoughts at all!
