assaulting castles more often, better ai unit mix

i've recently found myself getting back into mtw, but i've got a couple quick questions for ya guys:

1. is there any kind of mod and/or txt file change that makes the AI assault castles more often? i love fighting siege battles, but it hardly ever happens.

2. is there any kind of mod and/or txt file change that makes the AI produce better units, and pass on the weaker ones?

thanks.

Dont know about the first one, but the second one can easily be answered.
Open up Gnome unit editor and open the unit_prod file. Look on column 15, and change the really weak units like peasants to around 0 for each faction choice

thanks for the info man. i'll check it out.

". is there any kind of mod and/or txt file change that makes the AI produce better units, and pass on the weaker ones?"

WesW's entire MedMod is designed to do that. He's spent endless hours tweaking the column 15 AI build probabilities and the tech tree in build_prod13.txt to produce that exact result. Works pretty well. You should give it a try.

Are you talking MTW 1.1 or VI? In VI assaults happens a lot more often. the castles are also more important.
