I began a few days ago my first campaign with DarthMod 1.4D, playing with France in VH/VH. The very low income with this mod forced me to adopt a very agressive and expansive behaviour, as I destroyed the Milan faction about 10 turns after they first besieged my southern towns. My field tactics rely mostly on fierce bodyguard's chivalry to break through weakened or isolated groups of infantry, backed up with lots of archers. Excommunicated, threatened by the HRE, my strategy will now rely on strong alliances with Spain factions to face central european ones.

First of all, no CTD were ever experienced while playing this mod. Which is a huge performance. Battle physics are perfect, such as it feels painful to go back to another mod. Battle AI is good, however a bit too passive when outnumbered, as the ennemy won't try to get the high ground or hide in the forests. When besieging you, the ennemy will even stop moving while climbing the walls of the settlement. Finally, regarding the campaign, the overall feeling is good, the pope being extremely annoying as usual (I hope besieging the Papal states soon).
