If you are bored to crash ai eveytime, listen to me carrefully. I change some files in this mod and it's now perfect. I guarantee that you will lose to the ai. I've been playing medieval 2 total war more than 4 years and this mod is just perfect now with my changes. I tested ai for days and i will release this minimod. So what is the differences:
1) Buildings will be upgraded very easily and quickly.
2) I made ai more aggressive than ever. In very hard difficulty, ai will crash human
3) Easy to recruit units and game will be enjoyable
*** I changed only 4 files and it's about 1.17 mb. I am an expert player and i definitely suggest you to play but remember, this is for 4.3 version and not save compatible
