I'd say the quest givers in almost any game take up more time from your mission in-game than the actual missions and objectives you're there to accomplish. I remember the one side-quest that I never did manage to nail down was the Riddler's Trophy collection search that would allow you to take him down in Batman Arkham City. Was just too painful to pursue for prolonged periods of time, especially since some of them required you to play as Ms. Kyle to unlock part of the way to them, and then switch back to the Bat to acquire them.
