Pretend (?) you run a gaming company. If you could bring the biggest mobile game there is purchasable in stores, would you do it? If you're the largest game publisher in the world, then it's not such a tough question. Surprise surprise, Activision is publishing Rovio's Angry Birds for the Playstation 3, Xbox 360, and Nintendo 3DS, even though it's free on Android and available for way less on iOS.
What's way less? Angry Birds Trilogy, which includes Angry Birds, Angry Birds Seasons, and Angry Birds Rio, sells for a buck each for the iPhone. To match with DLC, that's $6 total, or $10 for the HD versions on the iPad. Again, free on Android. This new version? $30 for the 3DS and $40 for home consoles.
