This is like no other RPG I have ever played. I know there are other story telling games out there. I know there are other diceless games out there. This one hones in on taking a big concept history and zooming in like a microscope on the events and scenes that create that history. Players (there are no GMs) decide on a large period of history (the beginning and the end) then using the mechanics play out how that history came to pass.
Now this may sound like you are railroading the players, but you aren't. Each player makes sole decisions for how history plays out. They can describe a period of history (a barbarian invasion). They can, describe an important event during a period of history (the fall of the Capitol). Finally, the players singly or as a group can play out a scene from the history (the guard captain that single handedly holds back the horde so the emperor can escape).
The rules are simple and elegant and allow for the option to negotiate certain aspects of the creative process, while preventing the process from becoming a boring and homogeneous committee made history.
Really fun and has the potential to be used by GMs who want a history for their campaigns but don't want to invent it the whole thing themselves. It is also great for giving PCs in other games a sense of ownership of their campaign history they may not otherwise have.
Straight forward mechanics, good examples, plus designer notes. You won't have any difficulty figuring out how this game is supposed to work. All you need are note cards, writing utensils and your imagination.
(Frankly this is also a great tool for training young minds to think critically, or not so young minds)
Great. I am definitely recommending this to everyone I know.
