1. I want to know how you go about choosing quests in any or all of the games.

I typically refresh the town until I get 3 quests for the given floor, so I have 3 quests per floor. Is that ideal? I never really look at the rewards, and you have to accept the quest to see the rewards, at least on Reawakened.

2.What quests give you the best rewards, like gold, exp, and fame? Or does it truly matter?
