Sony AI patent will see PlayStation games play themselves when players are stuck

Why would you single out MMO veterans in this scenario?
Not op, but I took it as being because MMOs are the only one form of modern games where anyone really cares if the player cheats. So MMOs tend not to leave developer cheat codes lying around.
(Edit: Yes, other competitive games do exist, I guess.)
