Chris Buffa (Modojo): Electronic Arts' The Simpsons: Tapped Out is currently the top grossing video game for iPhone and iPad, a remarkable achievement. At the same time, it plays almost exactly like the countless free-to-play titles that also call the App Store home. Ultimately, it amounts to tapping the screen to make things happen, with the difficulty almost non-existent, since the characters, not the people playing, finish the tasks. And yet, it's taken the smartphone and tablet world by storm, despite a couple bumps that left more than a few fans upset, to put it mildly. That said, EA succeeded largely because the company took the extra step with the license. Quite frankly, it's made all the difference.
