^^ That would be interesting. Similar to how D.C. was originally designed with the street layout.
That said, I agree with some of the comments above. It's allowed us to have some uniquely shaped buildings that aren't simple boxes (or at least some of them, since we do, indeed, have many simple boxes as well). However, I also agree that several of the ones to the East can go away and never return. Won't happen, of course. Especially if Austin becomes a District.....
