jojoweb has done some cool stuff importing 3D objects from such sources as Morrowind and Zoo Tycoon, which got me thinking... I've asked but no one here seems to have SimCity 4, which could also have potential import possibilities. Here's another site that has all sorts of 3D models, developed in 3D Studio Max, which therefore leads me to believe that MAYBE they can imported as well (or perhaps we could go a-beggin' to the creators for an export into .nif or whatever?) I'm sure there are a ton of other games with 3D models, but the question I guess is whether they are compatible with Civ4's .nif format. Thoughts, anyone?
