I also liked the third world. It's still different enough from the first and second worlds, the storyline is different and the side quests are really fun. The world map music is also very beautiful in the third world. The only thing I dislike is that the castle with Zombie Dragons now has Zombie Dragons and (SPOILER)Exdeath Souls, so you can't be sure to run into Zombie Dragons all the time, meaning it was better to level up with them on the second world.
