I was just in a parking garage and it made me think about CoX and how tiny they were. The one I was in was long and tall and connected to the mall in multiple locations. Inside the mall, there were three floors with several spots where, if you were to jump down, or fly up, you could get to the different levels. Kind of like the "layer cake" cave we all hated, but if it were a mall with a built-in garage with any sort of realistic sizing and good levels of detail, I think that would be pretty cool.
