Seems the hatred of timed missions is in the air because of AC: Brotherhood. Time to vent. What are the timed missions that went above and beyond reasonable?
Dark Forces 2: Jedi Knight. The old classic escape from the crashing ship level. Not a lot of extra time, a mazelike interior, and just for fun everything is at a 45 degree angle making jump puzzles even tougher.
Assassin's Creed 2. One of the contract jobs has you killing three randomly placed moving targets, not a lot of time, and just to twist the knife a bit more the targets can't see you.... rather odd since you can kill them publically with no penalty, but target sees you a second before you slip the blade in, it's an insta-fail.
