From the introduction:
It’s about a group of friends and acquaintances living their lives, including one young person with an unusual, secret religion. Play is sort of about coming of age in a particular location and subculture of your choice, with no outstanding crisis beyond the rigors of life and circumstances.
What it’s really aiming at is a creative atmosphere of comfortable riffing, off the mechanics and off one another. The general activity is shooting the shit, without regard to focused conflict, to give rise to reflection or provocative dialogue. The goal is to discover “moments,” making snippets rather than episodes: more of a skit technique than a story technique.
