@Ahwaric: Sorry I'm a bit late to this, but in answer to your original post in this thread, I think you should create something you enjoy, i.e., the mod you want. I'm sure people will try it and give you feedback. I like the idea of bringing Slavic elements into the Doviello (the whole Varangian thing). As for Warhammer, I don't know how far along the Civ 4 mod got. If you have Civ 3, there's a completed Warhammer mod for that, which you can look at to see what they did. Civ 3's editor is more limiting than what you can do in Civ 4, but they came up with a nice variety for the different civs, I think.
