Abstract: A gaming system for training to modify behavior includes a trainer database for storing data input by a trainer that documents behavioral data corresponding to a player and is collected or observed by the trainer when the player is not playing a game offered through use of a gaming engine; a player device used by the player to play a game selected from a gaming database, used to generate player behavioral data uploaded to the gaming database and based on the player's interactions with the game, and used to interact with the trainer through the gaming engine; and an I/O device in communication with the player device or the gaming engine for collecting location or vitals data corresponding to the player as the player plays the game. Game settings can be changed based on the player's interactions with the game or based on the location or vitals data.
