Thanks for the info. A few more quick questions.

After I add the factions, how do I port over the VI units? Will it be done automatically?

How would make them get extra points for defending their homelands (since you said you can add points). I want the goal for these factions more to be holding their homelands and maintaing their independancy moreso than conquest.

Lastly, if I build pagan religious structures will my king actually convert to paganism or will he still remain christian? Do I have to program the faction to be pagan?

Thanks a lot.

(Incidentally, I think I'm going to do the Welsh too now, so all of the Celtic nations are represented as their own factions in MTW.)
