You read the title right; this mod is impossible to play. Tested this mod for the first time today... thought it looked nice on the screenshots, not to mention the good feedback it had gotten.
I played with Easy/Easy difficulty as the Picts (the only faction that was flagged as "easy"). To my surprise, most of my towns had terrible public order, economy and defences. I moved some of my troops to the most "angry" cities, and succeeded in making them "happy", but I stilll had angry cities that was out of reach from my troops. In these towns I built religious buildings. It could have solved the problem, if not for the 3 turn build time; after 2 turns, the towns rebelled and overthrew my holding on them. Then, in the 4th turn or so, one of my towns was attacked by another faction. My poor town had extremely bad defences, so I didn't even bother to try and defend it; I resigned!
This mod is in need of a major nerf! Otherwise, casual Total War-gamers like me will be unable to play it (which is sad, because I love this mod's setting).
