I like the idea of a side quest giving you information about the world, while the main quests only progress story/time. But sticking to the main quests would give you a bland Hollywood cliche, and only by finishing side quests you got info that could deepen backstories, reveal true motivations and flip your point of view to result in a "what the f..." moment for the gamer.

What if only side quests gave you experience/gold?
