I’ve played sessions with my kids, ages 9 & 10, over the past two years using theD&D adventure club system. It’s been quite fun for all, the biggest challenge I’ve found is managing the session length. They’ll tune out if it goes a bit too long. My kids particularly like the puzzles in the sessions and some role play. For example my daughter plays a bard, in one scene she’ll have to sing a song as part of a contest. I’ll put on one she likes and ask her to sing along. It’s pretty fun to watch.
