Genesys is the basic Narrative Dice System used in the popular Star Wars RPG by Fantasy Flight, but aimed generically at whatever setting you want to create. Yes, YOU create. There is work here for the referee. Fantasy Flight promises some future setting books for Genesys, but currently there are none available, so each Genesys referee will need to craft their own game using the tools in this book plus any creative imagining and borrowing you can add. Notice the cover illustration. The center is detailed and in focus, but as the eye travels out to the perimeter the detail becomes more sparse and the image less focused. This is a beautiful metaphor for Genesys. It is The Beginning of many great games, but there must be an element of do-it-yourself involved. Go into Genesys with eyes wide open and with a vision of what you want it to be and it can be a very satisfying game.
The Narrative Dice System uses Fantasy Flight "Genesys" dice - which differ from the Start Wars dice. You will need/want a pack of those to complete the game. I am not a huge fan of proprietary dice and that is why I knocked off a star in my rating. Otherwise, Genesys delivers. The Narrative Dice System facilitates "Heroic" play nicely and encourages players to engage in the drama and collective narrative that develops at the table by suggesting how the dice may be interpreted. The Narrative Dice System is a dice pool mechanic that tends to result in success with complications or failure with advantages. More improvisation is required of the referee than in a d20 or d100 system which are basically pass/fail. The real fun is to engage the players in helping to elaborate on what the dice outcome can suggest.
If you like generic systems, I think Genesys is a good one. All games suggest a style of play and Genesys seems to work best with an expectation of a heroic, cinematic style of game. Not sure how genesys would deliver on grim, gritty, realistic or horror style games. Character death is just not enough of a threat for that feel. But, hey, this is DIY, so by modifying the Genesys rules almost anything is possible.
