I'm gearing up to do the Bladder of Steel achievement of RB2 (Endless Setlist 2 without pausing or failing, which is six hours 15 minutes of straight playing, no pausing, no failing, no guide button, no batteries dying, no power failure, no bathroom, no food, no sleep, no RROD, etc.)
I've been lolling hard reading all these threads about people just peeing themselves about five hours in because they didn't want to quit and stuff.
Should be a good time.
