I was playing sim city 4 on my computer when the thought crossed my mind: it would be awesome to have mushroom kingdom things in it. Instead of houses, there could be mushroom houses. And City Hall could be Princess Peach's castle. Some of the environment hazards could be Bowser attack, Goomba riots, or Tweesters. You could commence trade with the Beanbean Kingdom or Sarasaland. I just thought that it would be cool. Any ideas or feedback?
