Is it possible to create a Rockband equvialent for photos?

Rockband has been a runaway success, not only in terms of game sales but also bringing about a powerful new model for music consumption:

The success of the video game Rock Band is drumming up revenue for the music industry.

Virtual rockers downloaded roughly 2.5 million songs in the eight weeks since the game launched on the Microsoft Xbox 360 and Sony PlayStation 3 systems.

The reason for this is simple. Games make music more interactive, more entertaining, more fun:

"Hopefully it helps evolve music to not just a linear art form but a more interactive art form," says Van Toffler of MTV Networks. MTV Games publishes Rock Band, along with Electronic Arts. "You look at a lot of 20-year-olds who are reticent to plop down $20 for a CD, yet they don't mind paying $25 for a DVD or $50 for a video game

Can we apply the same principles to images/photographers?

For the past few weeks, I saw my wife addicted to this simple iPhone game of 'spotting a difference'. The game was simple: 2 images were shown and the player has to spot the difference.

Today, I saw a similar Facebook game called Spotmania:

Is it possible then to apply the Rockband's music marketplace concept to these spot-a-difference games using photographs? Will the popularity of such games open up demand for unique or interesting photographs? Will such games create viable ancillary revenue streams for photographers?

Or am I just being silly?
