A system and method configured to enhance gameplay between users in an online game and to provide enhanced interest in virtual goods associated with collections of virtual goods through the ability to rotate drop rates associated with these virtual goods from time to time. The system and method includes the provision of functionality which allows providers of online games to periodically rotate drop rates associated with mystery boxes in order to maintain and/or generate additional interest in specific mystery boxes. As a result, it is possible for game operators to enhance revenue opportunities associated with these boxes even in the case where such boxes have been available for a relatively lengthy period of time and/or where players would have otherwise lost interest in specific boxes.
