Oh yeah did I mention that at a family gathering recently I ran a Fate game for kids between the ages of 4-9? It went pretty well!
Two of them had never even heard of an RPG and without even knowing about it being a thing they asked to pause after character creation so they could draw their characters
One was a unicorn that shot rainbow fire from its horn, one was a panda that was "cute, but also tricky", and one was (very broadly) "an assassin"
@cwebber I ran a few sessions with Clover, and it was fun to describe Kiki, the Delivery Witch, in Fate terms. I was able to get some of the + and - dice mechanics understood, but pretty soon we forgot about the them all together as we raced around the city delivering produce from Stardew Valley, while avoiding neko-slimes (from Slime Rancher), and verbally insulting anyone trying to befriend us merely because we can fly!
Dice might work with more kids, as the item of attention.
