I think games like No Thank You Evil (NTYE) and Hero Kids could help TTRPGs break through to the general family games market.



NTYE is a particularly good example in that it comes in an attractive box, with attractive books, cards, and aids. An adult that has at least played more involved board games is not going to be intimidated by the rules and can read through them and be ready to run a game in under an hour. The add-on purchase of the adventure building cards increases playability without having to hunt and pay for lots of adventures or spend lots of time building your own. After playing several time through my 7 year old was able to run me through an adventure using the adventure-builder card set. The only thing that I don't like about NTYE is the name. But it may help make the game more palatable to highly religious families. If the game was a bit less expensive I would be buying it as birthday gifts when my son is invited to his friends birthday parties.



Hero Kids is similarly easy and their pdfs serve as both an adventure and a crafting activity. You can cut out and color the paper minis, and print out battlemaps. Even more so than NTYE, aver a couple games, my kids (6 and 9 at the time) were creating their own adventures and running the rest of the family through them (the meat-grinder fun houses that kids come up with are hilarious). Hero Kids should do a kickstarter for a box set for about USD 20-25 that contains a printed rule book, some 2D plastic minis for PCs and monsters, some bases for the minis, so reusable maptiles (like those in their Minotaur's maze PDF adventure), some six-side dice, and an adventure book with perforated pages that you can pull out and copy to make more monsters/characters.



If you can make a box set, kid-friendly TTRPG, with some toy-like features (cards, flat plastic minis, paper battlemap titles) that sells for $19.99 and get it into Target, Games by James, Walmart, and other retailers, I think it would do well.



Kids that grow up playing and making adventures from early grade school, will naturally gravitate to games like D&D 5e and even more rules-heavy games when they are older. You just need to get over that intimidation hurdle that most TTRPGs present.
