8. The Simpsons Game - Press START To Play
No gamer profile is complete without the easiest achievement of all time. Even the achievement description has no shame in admitting it. This achievement requires you to press start on the opening screen of the Simpsons Game. That's it. 5 gamerscore for pressing one button. You should continue playing afterwards though as the game is surprisingly good. The easiest achievement ever... I bet that was Matt Groening's original vision when he came up with the show.
