Is the vanilla AI ruining your immersion by wasting its treasury on buildings in low-control provinces for 0 ROI, picking useless government reforms and estates privileges, relying entirely on peasant levies rather than a proper regular army, and creating horrific bordergore?
REAI (Rational Empire AI) is a comprehensive script-level overhaul that forces the AI to manage its empire like a calculating, logical state. By utilizing custom script injections and strict logic gates, this mod ensures the AI prioritizes a professional army of Regulars over weak levies, maintains a rock-solid manpower reserve, manages its government reforms optimally, and dictates clean, strategic expansion.
REAI isn't a "magic buff" mod. It doesn't hand out free population or hidden tax cheats to the AI. In the first few decades, the AI is simply laying its foundation—revoking bad reforms and picking better ones.
The real snowball effect kicks in during the mid-to-late game. Bad AI nations will still fail, but the smart ones will slowly build a rock-solid economy and a battle-ready professional core. Give it time to cook.
