Skrillex's maximal brand of American dubstep is very popular among folk responsible for video game trailers. So it's weird that, when the producer gets his own video game, it's nothing like a modern first-person shooter.
Nope, instead we have this weird Zelda homage called Skrillex Quest. In the game you're tasked with defeating strange digital artifacts, spawned from the dust you used to blow from 8-bit cartridges.
Not sure you'd actually call this "fun", but as an advertisement for Skrillex, it's pretty neat. It was created by Jason Oda, who has also created video game "ads" for the likes of TLC and Fall Out Boy.
