After playing this mod extensively this is what i found.

1. Beserkers are OP, completely unbalanced and too powerful. their axes need to be reduced from 155, to what? 100 power strike 10, ironskin 7....skill of 355.... -1 balance.

2. Changing cultures don't work, it also lists the old cultures, In more detail this bug causes your recruits to recruit native recruits or player faction, which i am not familiar with the troop trees on these or the equipment, i don't expect them to even come close to being able to hold their own vs custom troops. Can't give this a -1 cause its gamebreaking for me. Until its fixed anyways.

3. Minor faction spawn rate is too high. -1 gameplay

4. Minor factions only hate you, some are OP. -1 immersion/balance

5. Landownership, common miscalculation bug on assets, even perisno got this bug in latest patch, but much worst. -1 feature bug

6. Companions levels are too high, I found one that is like level 45, with no bloody skills, highest being a 3. Companions should all be relatively low level, so you can customize and develop them as you wish. I wish there a was a execute command.... -1 Customization

7. Can't read books, action ignored. -1 feature bug

8. NPCs spawn in player faction first town, you will find ALL of the npcs that contest the throne on ALL the other factions. -1 Immersion

9. Trade is always buggy, production, etc. Having a shortage of 1100 of everything is stupid, thus the trade system could use some work. Most mods ignore this though, that i have seen.
-1 Immersion
10. "Crush through blocks" attribute is missing and related weapons. -1 Nostalgic Feature

This mod is new suffers from balancing issues, some features are broken, and some odd script errors and npc spawns like in #8. It would seem that some features, even though you click the on/off, or things like auotsell doesn't work completely or some food items are treated as normal trade goods aka fine basket of fruit, not a food item. So far, I wouldn't recommend it yet in its current state, maybe after a patch or two.
