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.
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.
Im glad you feel enough shame for this bold-faced lie
