I will be making a Scotland module for my mod (check the link in my sig). I have already made Module Pack I, which has Hungary, Teutonic Order, Nubia and Phoenicia.
Currently I am working on the America's module pack, which includes Canada, Mexico, Brazil, Argentina, Gran Colombia, and Cuba.
The next one, Module Pack II, is going to include Iran, Vietnam, Minoa, and Songhai.
After that I am going to make the Europe Module pack which is going to be HUGE, so far I am thinking of doing Scotland, Ireland, Italy, Denmark, Switzerland, Sweden, Finland, Poland, Austria, Bulgaria, Serbia, Romania, and Ukraine. I might add more but I'm not sure just yet. At the rate I'm gonig the Europe module pack will probably be ready in, at the most, two months. But if you REALLY want scotland I can probably do that one first (after the other two module packs that is) and send it to you. But they will only work in my mod, because they will use some pre-existing flavored units. But in general its a good mod that doens't change the game mechanics too much at all (I just added Inquisitors, spy promotions, and seven extra religions that only appear when you select choose religion ala JARM).
If you have any suggestions for UUs or UBs for Scotland that would be appreciated though. I was going to have Robert the Bruce and Mary Stuart as the leaders. But I could be convinced to make a William Wallace or Rob Roy LH, we'll see how busy I am at the time.
The reason I brought this up, other than simple advertising, is that I make my modules so that you can easily insert and remove them from the mod without effecting any of the other XML. Which means they don't have custom music or diplomacy text, but I feel those are frills and making it easier for the user to customize what civs he wants to use is preferred over the diplomacy texts and custom music which does little for gameplay.
