What should be added to the top five from the previous installments?

I don't remember anything like that in the third game... :rolleyes:

What are you talking about? You enter a castle with a hero, right-click on a building, and destroy it. This way, you destroy the entire castle, and after a week, ghosts appear. Then you can rebuild the castle, either as it was before or as a castle of the hero's race! :)
