If you're worried about it not working on your GPU then you can probably rest at ease. Civ3 isn't GPU intrnsive but more CPU so even if it can't run on your Gfx Card it should run with software only.
And the only reason D3D or DD is the only supported GPU code in 3D games is that they have adv. and dis. adv. Direct Draw I think can say that object is behind that other object so I don't need to think about it
