The Simpsons- Tapped Out

EA's game based on the inhabitants of Springfield is surprising in a few ways. It's free, which is quite the thing, plus, although what many would deride as a 'freemium' game, it's more than possible to keep it going in the background, pottering away, slowly unlocking all of its content for free. Free-to-play done right, for once.
