>>102882133They all grew up with Harry Potter and figured it was a good merchandising scheme to have spin-off books that explained lore and world-building for the kids who like to roleplay.
From a business perspective, it really is a good idea for kids. I had one of those toy Pokedex's in the 90's and me and my friends would roleplay Pokemon after school at my house. I mean, I don't know how often kids roleplay anymore considering how goddamn advance video games have gotten for them. I don't know if I would have wanted to even have sleepovers if I had a copy of Breath of the Wild as a 9 year old.
