From the back of the book:
Quicker. Easier. Streamlined.
Remember when playing fantasy role-playing games was "quick and easy?" Remember the nostalgia you first felt at playing in a game? The "kinder, simpler" rules that make the game accessible even to younger minds? When plots were simpler and the story was heroic - "protect the kingdom, slay the dragon, rescue the princess?"
Simplicity is back. While trying to introduce someone to a role-playing game can overwhelm them with options and rules, this work is designed to keep things simple and presentable. You can drop this work into the lap of an 8-10 year old who has never played RPGs before and get him an understanding of and an ability to contribute to a game, completely by the rules, in an hour or less. More experienced gamers will already be familiar with the material in this work, but may wish to use it to introduce their friends into gaming. Show them that gaming is fun!
This product is intended to bring to the table a "core" system compatible with the World's Most Famous Role-playing Game that is so simple and streamlined that you can drop it into the lap of an 8-10 year old who has never played RPGs before and get him an understanding of and an ability to contribute to a 3/3.5E game, completely by the rules (albeit with less tactics since I have deliberately excised some of the options in favor of simplicity) in an hour or less. That's a tall order, but I think it can be done.
Note that this is focused on players, not GMs, so you will need to have an experienced GM to run things, but this is very much an "introductory" product designed to get the newcomer to the game up to speed in a minimum of time and with a minimum of effort.
