9. The Bladder of Steel Award - Rock Band 2
This one isn't so much a provocation like the above as it is flat-out cruel. Rock Band 2 features a setlist called the Endless Setlist 2 which, as you can guess, features just about every song in the game back to back without any downtime. To complete the achievement, you must play through 84 songs without a single fail, and to make things even more punishing, you can't pause the game to go to the toilet (you're going to need a bucket and a friend prepared to pull your zipper up and down, or better yet, don't wear jeans). The challenge takes close to 7 hours, meaning that even if you can resist the urge to pee, your hands are going to end up knotting up after the two or three hour mark (trust me, I know). By over double that, you're probably going to be suffering severe cramps, which combined with the increasing difficulty, makes this an epic challenge even for those who can comfortably beat most songs on Expert. Pro tip: make sure you use fresh batteries, because if they run out, the game will interpret this as a pause, and knowing sod's law, it would probably happen during the final riff of the final song, too.
