Earlier this week I had an article of mine posted up at Gameranx. It discusses how Majora's Mask's side quests work were unique and how it's fundamentally different from other games' side quests. Here's an excerpt and check out the full article here!
"Games nowadays have sidequests that tend to be boring, monotonous fetch quests with a little bit of action here and there. The challenge is also nonexistent. Mass Effect 3 is a great example of this. You look on the map, click the destination, see some cutscenes, kill some dudes, and that’s it. How boring is that? In fact, there’s no real way to mess up and fail the sidequest other than to just die in combat."
