Least Favorite Character: Mr. Costington
He only interacts with two buildings, only two of his tasks are visible, and for a character voiced by Hank Azaria all he has is that single grunting noise. He doesn't even have his signature catchphrase.
Least Favorite Character Skin: Gorgeous Grandpa
It was a weak episode, and I just don't like it.
Least Favorite Building: Tie -- The Springfield Office of Unemployment & The Gypsy Fortune Teller Shop
I don't care for buildings with parking lots already figured into the design. It makes them difficult to place.
Least Favorite Decoration: Springfield Park Entrance
It's the only thing I've ever sold back in-game. It's 1x5 length makes it impossible to 1) make a symmetrical park wall and 2) place a road under it to create a walking path.
