I spend HOURS reading these as a kid
(hexbear.net)
Fuck iPads, having kids look at glossy pieces of paper with diagrams of castles and pictures of cool pirate swords is what the children need.
adults need these as well, just have to add up to date references and better illustrations than the 3d garbage that has replaced a lot of the art in these books
could just be marketed towards adults as a curated hobbyist subreddit knowledgebase, kids are mostly only there for the pictures anyway
