But we all love Norse Pagans more than muslims

. Muslims have the least interesting game starts in 1066, while the opposite can be said for the norse.
Then again the holy war system will need a MAJOR nerf for a pagan dlc to work. Ck2plus managed it quite decently.
EDIT:
On the topic of pagans being an inferior form of christians, I have to disagree. These are 99% of your ancestors that you are making fun of man! Show some respect, please. And thats why pagans are more interesting.
If the pagan dlc gives us opportunities to meet a druid/priest and convert to the old faith, i would be hella excited ;P
