1. A method for building and utilizing interactive software system predictive models using biometric data comprising: providing an interactive software system; defining biometric data to be obtained and analyzed; providing one or more biometric data collection systems to obtain the defined biometric data; monitoring a user's interaction with the interactive software system and obtaining user interaction activity data indicating the user's interaction with the interactive software system at defined times; using the one or more biometric data collection systems to obtain biometric data associated with the user at defined times as the user interacts with the interactive software system; correlating the biometric data associated with the user with the user's interaction activity data at the defined times; obtaining baseline data associated with the user, the baseline data including data indicating when the baseline data was obtained; analyzing the biometric data associated with the user and correlated to the user's interaction activity data and the baseline data associated with the user, to generate emotional pattern predictive model data representing an emotional pattern predictive model associated with the user; based, at least in part, on the emotional pattern predictive model associated with the user, modifying one or more features and/or supporting systems associated with the interactive software system to customize an interactive software system user experience to the user; and presenting the customized interactive software system user experience to the user.
