An interactive presentation and/or entertainment system, such as interactive personal computer software and/or interactive television, allows a participant to modulate the emotions of a character or personality (720), thereby influencing the branches (750) to an interpersonal relationship over time. As a result, a broad range of computerized dramatic situations or stories are presented that closely resemble human interpersonal relationships. Source image/sound data may include prerecorded video, prerecorded audio, computer based audio, computer based imagery, computer generated dialogue, and/or computer general characters. The range of emotional choices made by a participant may include all emotions that human beings can experience and, in turn, represent by thought, word, or action. Emotions that indicate personality rather than mood are presented, such that the ebb and flow of a character's emotional states are exhibited over an extended period in the course of many situations and activities, instead of as mere ephemeral reactions to isolated incidents.
