Angry Birds - possibly the most popular mobile game ever made. Over the few years the game has been available, it's like there hasn't been a single day without Angry Birds in the news. Rovio Mobile, the developer of the game, has made sure that the Angry Birds mania grows to tremendous proportions by now only working on improving the game, but also through merchandizing and clever marketing. A bright example is the recent news story that Formula 1 driver Heikki Kovalainen is going to race with an Angry Birds-themed helmet.
Realizing that it has a money-making machine on its hands, following the launch of the original game, Rovio was dedicated to producing mostly more-of-the-same type of sequels of the game, with Angry Birds Seasons and Angry Birds Rio. While these newer games were pretty good as well, having that familiar cute cartoonish style, and the same addicting gameplay, Seasons and Rio didn't bring almost any new features to the series.
