A system includes a display device, a memory storing 2-dimensional (2D) content and 3-dimensional (3D) game content associated with a content item, and a playback engine. The playback engine is configured to receive the 2D content, the 2D content including one or more reference identifiers (IDs), display the 2D content on the display device for a user and, during display of the 2D content, receive an indication of a transition event. The playback engine is also configured to determine a transition reference identifier (ID) from the one or more reference IDs, identify the 3D game content based on the transition reference ID, render a 3D game environment based on the 3D content, and transition the display device from the displaying the 2D content to providing the 3D game environment.
