Wow did this get derailed. I guess gamers really are a bunch of ADD having asses. Anyway, I had the same thought playing and decided to check it out. There is a single building in the financial district that is taller than the empire state building and it moderately approximates a single world trade tower. Considering I lived on the border of the bronx most of my life, and still live in nuclear explosion distance (only from a Zsar Bomba) from Manhattan you can take my word, for what it's worth, that this single building, in one way or another, represents the WTC. I suppose it would've been tacky to put both of them in there, and without either the skyline just kind of sucks. You can use the chopper to measure height, and WTC 1&2 were the only buildings actually taller than the empire state building.
