In game missions!!!!

If you add missions from villagers or a story line for each tipe of village the game will always stay interesing. For example: Savannah villages need different type of resources to survive. Mission: get the recources from nearby villages or other biomes. Or each villager can give missions where you get extra rewards instead of traiding things you dont need. Not everyone want to download moded worlds from the marketplace!! Most players want everything to be just normal minecraft that improves with every update.
