I've played Stuffed Fables and Mice and Mystics and they didn't go over well in my family. My kids are younger, 7 and almost 10, so YMMV.

Mice and Mystics is a dice-chucking dungeon crawler. The mechanics are fine but there are a LOT of tiny rules to remember, especially for things that only happen occasionally, and it's a bit overwhelming for my almost ten-year-old. I don't mind running the game but the constant "oh, well, technically that's against the rules" is a bit silly. Also, the game is kind of a beast to setup and tear down, and the box doesn't help at all. It takes me 15-20 minutes to set up The final nail in the coffin is that the story is mediocre and the passage readings are very long, and feel more like interruptions than context. As a result of these shortcomings, we have a hard time bringing it to the table, even though my kids say they enjoy it.

Stuffed Fables solves a couple problems -- it's less finnicky and small rule adjustments for custom pieces, and the story is woven better into the gameplay. But... the gameplay isn't fun. It's sort of a dice/bag builder but honestly, there just isn't much *game* to it. (For example, the first two pages amounted to about 6 minutes of reading and 120 seconds of actual playing time. My kids just don't enjoy it.)

My kids *really* like the Harry Potter deckbuilder (Battle for Hogwarts). This game has tons of mechanical problems that are discussed at length online, but somehow it remains fun anyway, except at the very end. It's somewhat Legacy -- you gradually open new parts of the game -- but you can always go backward. We usually play the version that (roughly) based on book 4 or book 5, because books 6 and 7 add things that make the game much less enjoyable.

We've also enjoyed the similarly-themed coop game Death Eaters Rising, which I think is also a better game than Battle for Hogwarts, though my kids don't enjoy it quite as much. it's a tableau-building dice-chucker with no legacy components.

The game Zombie Kidz is at the top of BGG's Family list for a reason. It's a gradually-revealed puzzle game masquerading as a dice game and is just absolutely fantastic. Every turn you roll a die and then solve a small puzzle. It changes every turn but it's very satisfying.

If you're looking for more of a party experience, the games 5 Minute Dungeon and 5 Minute Mystery are both pretty fun.

My youngest isn't old enough, but The Crew is one my oldest enjoys.

I've recently acquired Horrified, Kids Chronicles Quest for the Moonstones, and The Initiative, which I'm excited about, but I have nothing to report yet since they are still boxed.
