The Pleasure Framework is a collection of thirteen categories to describe pleasure in interactive works. It was developed by Brigid Costello in 2007 in order to evaluate a person's experience of a work. The thirteen categories are: creation, exploration, discovery, difficulty, competition, danger, captivation, sensation, sympathy, simulation, fantasy, camaraderie and subversion. Costello states that the framework could possibility be used in the design, conceptual development and/or participant evaluations (Costello 2007: 370).
