Actually, looking more carefully at Civ IV units, I don't think it'd work at all: partly because the models I used were far more detailed than Civ IV ones, and partly because I didn't use all-over skins like Civ IV ones, but just textures for various props and things where required. So even if they were 3ds I don't think it would work at all. I can PM you one if you like nevertheless, but I'm dubious!
I'm sure I could definitely get it to work. PM me one if you want to and I'll make it (but I doubt it will get any use as it would be too demanding with all the polys and multiple textures).

Also got rid of the beard and the bag to lower the polys a bit more. The point is that it works though
