I would say some huge video game franchise (not mentioning my favorites here).
They already showed that they are willing to cut 30+ hours of footage to match the screen to whatever is happening in the game, so I guess in cooperation with a studio or publisher they could make the whole "game in the game" incredibly interactive (and not like Gottlieb Super Mario).
Edit: Plus, they could get all the assets such as music, sound effects, 3D models, sprites, etc.
