The 7 and 5 year-olds in my household love this. You can use it to tell your own stories, you can make it as easy or as difficult as you like.
We've incorporated our actual lunchtime into one of the adventures by "stopping at a farm to ask for some food and paying by helping with a task".
At first the idea of fighting creatures was too scary for the then-4year-old, so I came up with some simple questing (the herbalist needs you to take something to another village). But now the Warrior and the Healer have rid a basement of rats, faced the Minotaur, and received a reward from the dead King in the tomb.
The "empty" character sheets have filled countless afternoons by giving the children a framework to come up with their own monsters, classes, heroes, and items. There were shrieks of excitement when I revealed that they could use the templates to create an entire "HeroKids" set in outer space. This goes on my list of "best things I ever bought for the family".
