This disclosure relates to a system and methodology for dynamically adjusting a game based on predictions made during game account creation in accordance with one or more implementations. The system may be configured to receive user information included in platform level accounts which were previously created by users on an online platform and assign one or more user types to the user based on that user information. The system may be configured such that game adjustments associated with one or more user types for future play by users associated with that user type may be modified over time based on historical and ongoing game activities undertaken by users associated with one or more user types.
