I have not played any Fire Emblem or Dragon Quest games, but it doesn't appear that those games even have quests, so... of course the quests don't give experience because they don't exist. I guess maybe Sandbox Mode (which made no sense at all to me initially, because I figured the game was already sandbox, being purportedly a management game) is more like those non-quest-based games. If that's the case though, it's really poorly tagged, and the Story Mode is incredibly poorly conceived. Should just be under RPG, not Management, and shouldn't even have a Story Mode.
