Alliance — Michael A. Ventrella

The Alliance Live Action Role-Playing game has chapters all over the country and this rules system is based on over 20 years of use. Included are large sections explaining how a LARP works, what you can expect to find, advice on how to get the most out of the game, and plenty of pictures, charts and graphs. The rules themselves are easy to understand and designed to provide the most fun, so players can jump right into the game without having to spend hours studying or arguing over silly details.

Michael A. Ventrella is one of the fathers of modern live-action role-playing games in the United States, having helped form the first major LARP in 1989.

This edition also includes table-top rules if you don't have a chapter near you or don't feel like getting out for the exercise!
