I would have chosen the programmers head but from what i know it is based somewhere near the philippine sea.... but still it would be great to know if they based it on any real place..... that would be crazy, a crysis in a REAL city, ala Flight Sim X.... but with full 3d buildings, mountains, and landmarks
