Jetpack Joyride is one of the best games of the year, period. The game is simple to play, incredibly addictive, and the developer has continued to support it with a series of free content updates that add more to see and do inside the game's world. The gameplay may be simple—you touch the screen to go up, let go to move down, all the while collecting coins, avoiding obstacles, and using different vehicles—but the game's design and execution are some of the best in the business.

It's also worth noting that we live in a world where for-pay updates are the rule, not the exception, and Halfbrick Studios continues to release new content for the game... without charging for any of the updates. We talked to Halfbrick's Chief Marketing Officer Phil Larson to explore about why this strategy makes sense for the company.
