A simple game to introduce young children (4 and up) to RPGs. The rules are basic enough to only take one page and general enough to cover most situations. Gameplay is easy and only requires D6, D8, D10 and D12 (there are rules for only using D6, but I think they would make the game harder.)
The book explains the game, simple character generation and gives 4 example settings for playing, with adventure seeds for each of them. The book is nicely illustrated and the illustrations themselves could be used as adventure seeds.
The book is printed in quite large text (I like this, I'm tired of squinting at tiny text in RPGs!)
