Does anyone know if the collateral included in CivCity: Rome is compatible with Civilization IV?

Don't know what CivCity: Rome is? Well here's the link for it: http://www.2kgames.com/civcityrome/civcity.html

what do you mean by "the collateral"?

Collateral means art files, building and unit models, sound files, etc. I know that you can take the collateral from other games and put them in Civ4. I just want to know if you can do this with CivCity: Rome as well.

Lopez, I believe it would work perfectly (but I don't have the game and don't plan on getting it). I even think the file format is in nif, the only problem that would face you is the most probably high poly count, I would expect it to be so because it is more focused on the buildings than civ4.

I have tried getting buildings from Sid Meier's Pirates, they would work perfectly, but would need their polys to be reduced to suit civ4.

But how legal would that be?

I was talking about personal use.
