Enochian chess is a strategic four-handed game, requiring tactical game settings, piece movements and rules. It also provides insight into both external and internal influences of the self, and it shows the complex movements of archetypes and their interactions with each other.
Good overview of Enochian Chess. I don't plan to build, buy, or use the system but it was a good read. If you're interested in how games and gameplay can be used for more than entertaining diversion you'll enjoy this.
