A wagering game system and its operations are described herein. In some embodiments, the operations can include receiving first application data from a first application, where the first application data describes a first characteristic of first content from the first application. The first application presents the first content during a wagering game session. The operations can further include determining a relationship between the first characteristic and a second characteristic of second content of a second application that presents the second content during the wagering game session while the first application presents the first content. The operations can further include modifying the second content dynamically based on the relationship between the first characteristic and the second characteristic.
