I don't know what you have done to TW Warhammer, but the current state of AI cheating is ridiculous.
AI can recruit more units than allowed in one region. I have seen multiple armies recruiting simultaneous in one region.
They do not care about money. And they can confederate in a blink.
All that is done even in normal settings where I would assume that the AI is almost playing fair.
The game is still beatable BUT F.... BORING!
It is discouraging to see AI cheating so obvious. Playing a campaign is so exhausting and I am very sad what you have done to this game meanwhile.
Do I really need to install a mod for no AI cheats even on normal?
It is nice that I can tweak everything with mods and I will do that now, but somehow sad I need a mod to enjoy this game and not going mad.
