I don't know how widely this has been talked about, but I just found Jimm Johnson's version of an attribute-less, extremely simple D&D game for kids. It's very much in the tradition of the microlite games. I'm talking the kind of game a four year old could play and enjoy, while remaining a bit faithful to the game we all love.
The PDFs (and picture of his sweet Dungeon Forge setup) can be found on his blog - The Contemptible Cube of Quazar - here at this link. Very nice and thank you, Jimm! I can't wait to give this a whirl.
