Speed modeling for Cities in Games

 need to build a city level. With hi rise buildings, much of lites, etc. So, how is better to create buildings. To build each building in 3d tool, or create buildings from modules?

Little description. Buildings will be very hi. Like in "Blade Runner" or "Johnny Mnemonic". This is cyberpunk style, so you can imagine size of level and buildings. In some of them player can enter, and walk throw...

Idea#: I'd say write a script that generates the whole city from scratch. Mutch more interesting than spending hours building each building

the script will be creating buildings that are primitive Game objects 

============================================================================================================================================================================

Well, the fastest way, without using some sort of a script setup, is the block the whole city itself out with primative shapes, and then detail it down from there, you can decide what buildings are relevant enough that people will need to go inside them, and put interior stuff in those if thats how interactive it needs to be, otherwise just shape the outside of the city. By blocking it out first, you also insure the scale is how you want it
