I'd treat this the same as a photography project, it's pretty analogeous to using a camera to reproduce imagery of real places.
Photography copyright law differs widely by jurisdiction. You'd defiantly have to check the laws in your region, but a general rule of thumb is hat if you're on your own or public property when you take it, then the photo is probably ok, but if you're on private property then the owner can dispute your copyright.
While that is true for private photography, news reporting, commentary, and various non-commercial and fair uses, it is not true for commercial uses.
For commercial use, you typically need a property release (similar to a model release) that certifies that you have permission to photograph. The release covers both trademark and copyright.
Famous buildings and private landmarks are frequently trademarked. Most famous skyscrapers (Chrysler Building, Transamerica Tower, World Trade Center, New York Stock Exchange, Rock and Roll Museum, etc.) are have multiple trademarks. Most casinos have trademarks on their designs. Many famous signs are trademarked, such as the Hollywood sign and the 'Welcome to Fabulous Las Vegas' sign.
For commercial use, such as a game, you absolutely need your lawyer to help get permission for using any existing structure
