From the Introduction:
This game is a role-playing game. It was created as part of the 24 hour Role Playing Game contest on the rpggeek.com web site. If you are reading this, you probably know what a role-playing game is already. In this game, a game master will prepare and adventure for the players. The players will create characters and explore the GM's world.
The theme of this game is that the players will take the roles of kids between the ages of 5 and 11. The kids will go back in time and have adventures. Perhaps they will witness historic events. Perhaps they will encounter unknowns in history and help them out. Perhaps sinister things people were not meant to know await. Regardless, the kids will have to solve their own problems without adult supervision. Luckily, they'll have the wisdom of the future to guide their actions.
This game's mechanics use a system of coins. While dice can be used as a substitute, the coin system was created to allow the system to be as minimalistic as possible. The author wanted to be able to create a game that used materials he could have obtained when he was growing up.
