I think you missed the point, and probably because the OP didn't carry the results of the 'experiment' out to its conclusions.
The OP was suggesting that we use games to make concepts in quantum mechanics more intuitive to KIDS. I've always wondered if we can bring the concepts and teaching of harder concepts, to kids at younger ages, if this won't spur more quicker advances because less time is spent in the more valuable years simply trying to grasp current ideas.
For example, there was probably a period where basic algebra was considered a "college subject" and not fit for teaching to anyone under the age of 18, yet in most places, the concepts are now taught in high school and sometimes even earlier. Calculus is now becoming a normal high school subject. If we can get these ideas into kids' minds at earlier ages, then later on expanding on the concepts won't be as time consuming and we can move past this period quicker and into more theoretical realms. My brother who is also a physicist often wonders if we could make Lie Algebra regular 12th grade curriculum, what that might do to the advances in math and physics.
