This sounds psychotic. An over-controlling fedora's approximation of what good academic parenting looks like. You just want to create your D&D partner. You'll probably succeed lol.
The self-servedness vs intensity of the management of said goal is what is different. Wanting your child to be healthy is good. Steering your child to be a D&D player is questionable.
Not every parent has the time or energy to do so, but i certainly thought i was on the more relaxed end of parenting. I'm glad i appear to be different online! I will take the intensity of my parenting as a compliment.
PD - I never played D&D. If there were any non-RPG games that were extremely plot driven or written, i'd be all over them.
Action games turn out to be heavy on clicking, low on reading.
If not, why not ? Aren't you managing their food intake ?
So, what's so different from managing their information diet ?
