A WORLD FROM NOTHING: The most general use of this book is to create a realistic yet randomized version of the downtown area of a United States-style major city from scratch. The EX NIHILO MVNDVS system will generate everything for you. The system will generate every building on every block, and will do so in a way that is in line with what one would expect given the statistical distributions of building types, heights, and uses in modern major cities in the United States.
EXPLORATION: The second general use of this book is as a tool that guides the exploration of a modern downtown area. For example, the physical state of the environment on a building-by-building and block-by block basis, the nature of any human or non-human activity, the number and types of vehicles encountered, et cetera. Additionally, the system will guide your exploration of each building on a floor- by-floor and space-by-space basis. Providing these types of details will allow you to focus more of your attention and energy on the core narrative and gameplay experience itself. My sincere hope is that this system allows you to observe, react, and immerse instead of spending time in a writer’s block-type state making rolls on non- descriptive tables trying to answer minor questions.
ITEMS: A third use of this book is as a tool or supplement for looting or scavenging in a modern urban setting. This book contains generation tables for eighty- two unique types of buildings and random item tables for over one-hundred unique types of spaces and twenty different types of vehicles. The random items tables contain a variety of items that one could reasonably expect to find in those specific types of locations and spaces, along with a few things to keep the game interesting.
NARRATIVE: Finally, EX NIHILO MVNDVS includes three thirty-six-item random tables that are aimed at helping you develop your story and drive your game narrative forward in interesting ways. These tables include leads that can be discovered, rumors that non-player characters might disclose, as well as pleas for help that non-player characters might make.
