Interactive Literature is a family of live-action RPGs, all self-contained. Typically, the scenario and all characters are written by a single author. Games run in size from 6 players to as many as 70.
The games use an extremely simple, card-based mechanism for resolving actions beyond the scope of simple conversation: Combat, Magic, Thieving Skills, etc. An IL game does not allow physical contact, and all such interactions are resolved with card play.
Interactive literature emphasizes player-to-player interaction: Information gathering, scheming, plotting, and betrayal. One or more GMs are present to facilitate gameplay,
