To paraphrase Oscar:
To build one ordinary tower looks like misfortune, to build two looks like carelessness.
Or, attributed to Voltaire;
"Once, a philosopher - twice, a sodomite!"
Personally, I just think building twin towers on a single base more often than not shows a horrible imaginative deficit. Or it shows finances playing out architecturally at the most banal level. It's seldom "so nice we had to build it twice!". It's more "you don't have a choice but to put up with it". Thanks a lot.
It's a good thing most people don't look up and care - Southcore wouldn't have a streetlife otherwise. Then again, if more people looked up and cared...
Anyway, the Entertaynment Diztrikt doesn't have a great heap of lots large enough to stuff multiples, twins and clones on. Though the individual towers are generally so ordinary on their own, they're pretty much accomplishing the same effect with no effort.
