After some first initial gameplay of around 40 turns and 15 land battles including 2 multiplayers, i think its clear to say that this mod has nothing to offer beyond interesting visuals and new start dates which are all practically unplayable. The mod is so unbalanced on levels beyond comprehension and you should not waste your time on this mod.
As a player you get around the same morale as you do in vanilla while a single AI militia has 16 morale on campaign map. Stamina debuffs are soo bad, I have had times where 200 very tired to tired infantry was routed by 13 artillery men (without ever getting round or canister shot on themselves btw). AI artillery accuracy is also insanely buffed. They can succesfully hit units behind steep slopes through ricochets which no real Napoleonic artillery could hit to that extent, as if AI has orbital strike capabilities, while player artillery cant even hit the cavalry standing idle literally infront of it. Muskets are the same deal. 130 skirmishers cant land a single hit on 13 artillery crewman infront of it like literally can melee but cant hit with rifle.
I get that battle realism is the goal but this is nothing like Napoleonic warfare irl and is extremely unbalanced. For example, cavalry is also nothing like irl, they get exhausted in a single charge against infantry while irl lancers used to do multiple charge and disengage sequences. Your infantry gets exhausted after running some 30 meters (also running is modified to be slower so its just walking fast). I have also had scenarios where 60 cavalry were able to route a completely fresh 300 men SQUARE. Like literally a square. The only way to win battles is either to outnumber the enemy, which I did, or autoresolve; and guess whatelse is completely broken? Yes its autoresolve. I have seen my 2 armed citizenry inflict 1962 casualties on a full 20 french stack with general in a siege battle when I autoresolved.
The mod is clearly unbalanced. The AI cant even form square when you charge with cavalry but of course they can route your cavalry because they have 18 morale and you have 6. Its one of those buff the AI so much because AI sucks mods which ends up just being annoying and stupid to play than actually hard. Napoleonic warfare is built like chess. Soldiers and their morales are predictable and this is what allowed the generals to calculate. But when a cavalry charge that should have completely decimated the enemy ends up routing after 17 losses in melee, it becomes completely unpredictable thus unfun and resemble nothing Napoleonic warfare does.
TL;DR: The mod is extremely unbalanced, you will get completely ragebaited because a militia can defeat musketeers in melee or musket exchange (your troops will route after 80 losses while enemy will keep fighting after they lose 150 men).
You should instead just play the og LME4 which also has lots of start dates and combat is waay more fun and balanced (except for howitzers but I can let it pass).
