It's about 50/50 I pulled them from the game but had to spend a lot of time getting the textures right. I then created the city from scratch one recreated building at a time.
In the end it's the same as in the game but I had to put a lot of labor into make it so.
OH! unexpected. I'd like to know more. contact me (user name at gmail) and maybe I can speed your project up. I was not efficient in my optimization but it might help you.
