I tried to do this mode and figured out how to start.
Here is what I did.
Start -->
0. --> got forced citizens --> raised them --> they are not strong and die easily --> couldn't get this troop type often --> failed
1. --> got Mercenary --> spammed cavalry Mercenary -> no money --> failed + Mercenary calvary is too weak to use
2. --> got Mercenary --> spammed range Mercenary --> got town --> getting attacked by 1000+ men --> failed
so I think I will do massive range Mercenary next game.
---------------
Note: at first, I thought I would try to get castles but since they are rare to besiege by AI so it was cancelled.

This mode is really hard and the game often likes this.
first --> everyone makes a truce
30-40 days later --> declare the war, targeting on cities
about 60 days later --> DK comes and gets about 4-5 towns then stop and start to lose
...
After playing for a while, I still feel that DK should get more cities or ruin the map more than this like
Sword of Damocles : imperial invasion (about 80+ lords invading the map and conquering all the map at the end like zombies.)
Another thing I found out is when I hit praven queen by using ivory arrow and a good bow(15p), she got only 30+ damage... on the first shot... oh well...
Also, I have a question. What the weapon that swadian priest uses? (blunt weapon)
