I love mods in general. However in the case of Civilization I stay FAR away from mods. I've been playing Civ since the original and since Civ3 I've been trying mods. I don't like them. Often I find myself annoyed with the changes... some of the changes feel the person said "Wouldn't it be cool if... xyz rule change" and then the game feels broken. I have faith in the developers and I paid them good money to make a product and refine it if needed. Mod's for me, are an unwanted addition to an already fine game. But if I play Neverwinter Night I want my class mods... the ones that add like 50+ classes to pick from. For me that's fun. More choice... but Civ mod additions just don't have the same quality as the devs. Again, in my opinion.
