Heya, I've got 50+ custom buildings complete. If I have enough time I'll upload them today. Here is a picture of some of the latest. One thing to note is because there are literally so many different custom buildings in this pack, if your playing with Direct x 9, then you will get pretty massive polygon counts. I'm using xp at the moment because my main computer is getting fixed, but the city would run almost twice the frame rate with Direct x 10.
The city in this picture is about 500 by 500 m. Now that might not sound like much, but there are about 100 buildings, 80 or so which are different (and about 50+ of them designed by me). You can think of it like this, the map has about 4 times the number of different buildings compared to pinecity, but takes up less space as the buildings are scaled realistically so there is a gradual increase in size and scope. Really, you could make a 2 x 2 km map of these buildings without it getting too repetitive, its just you would need a kicking ass computer.
