Publishers looking for a quick buck don't need to focus their efforts solely on the iPhone. Sony's Susan Panico touted the values of PSN development by providing a case study on PixelJunk Eden, Q-Games' third PSN-exclusive title. Panico told the GamesBeat audience that "PixelJunk Eden made its return on investment within 24 hours." Sales after that period become pure profit.

Of course, the success of Eden is a little unsurprising, considering the popularity of PixelJunk Monsters. Regardless, it's impressive that a small independent studio was able to create a trusted franchise exclusively through the PlayStation Network. With so much green made off of Eden, it's no wonder Q-Games is working on an expansion for the game. Eden Encore will be available in April.
