Ideas for a spin off game called "Quest mode" - Part 1

I think that Mojang should add a spinoff game called "Quest Mode". In quest mode there would be a quest command centre where players would receive quests and gain rewards from completing them. After they choose a quest to complete, they would be automatically teleported to the beginning of the quest. The quest could be anything from clearing a dungeon or a small castle to going into a volcano to defeat a fire lord, and make a deal with a phoenix or saving an underwater kingdom from an evil sea dragon whose lair is a gigantic ocean temple. Upon completing a quest, players will be automatically teleported to the quest command centre where they would receive a reward. They would also level up the further they progressed. Each weapon would have a different strength and power level. -Written by a student in my year 4 class
