From publisher blurb:
The Protocol game series is a collection of roleplaying games stripping away all pretense and getting to the heart of storytelling. Each game uses the same basic mechanics — vignettes, interrogations, interludes, and ensembles — to tell non-derivative stories. Every player has all the tools he or she needs to create interesting characters and environments for their favorite stories. The Protocol game series uses a simple method of shared storytelling with charts, motivations, character interaction, and plot.
Every game stands alone. Every game shares a commonality. In the Protocol game series, each story explores disparate characters dealing with adversity in a dramatic fashion.
All of the Protocol Games use the same basic mechanic, but with very different results. Games can be played with or without a gamemaster, though without is the best method. Players only need paper, pencil, and a deck of cards. No dice are necessary. Some kind of token for drama point can help, but aren't necessary.
