I’m glad you mentioned this edutainment strategy. There is an existing product line out there, I forget the name of it, but it teaches children (and adults) biofeedback by using existing Playstation games. Basically, the creators of the game use biofeedback monitors as if they were the X button on a Playstation paddle. You learn to relax your pulse, galvanic skin response…stuff that a lie detector measures to control the avatar in the game. I will try to find that info, because it is really interesting stuff.
