Of all the games that have landed in app stores, none has had quite the same cultural impact as "Angry Birds." Since the game's launch in December 2009, it's been downloaded more than 500 million times, spawned multiple spinoffs, and in total, had more than 200,000 years of gameplay. Now, these fuming feathered fowl are slipping the surly bonds of Earth in "Angry Birds Space," the latest iteration of the game by Finnish-based Rovio. But if you've already followed the Angry Birds to Rio and weathered the Seasons with them, is it still worth 99 cents to blast off into the final frontier? Yes.
