Xeryx's release of XAI 2.20D+ allows me the opportunity to bring this magnificent AI to fellow users of this mod!
Guys, this AI is seriously the BEST. It should give even seasoned M2TW players a great challenge. It will consolidate its armies into large stacks, and attack you very aggressively. Also, I believe this AI has the most sensible diplomacy.
All the credit goes to Xeryx for the AI, Candelarius for his outstanding Grand Unit Add-on Mod, and of course Unspoken Knight for giving us Retrofit. I only threw the files together. Please give feedback about the AI in this thread: http://www.twcenter.net/forums/showthread.php?t=147477
Battle AI is included as well.
Instructions: Extract all files except descr_strat.txt to your M2tw\mods\retrofit\data directory. Descr_strat.txt goes in M2tw\mods\retrofit\data\world\maps\campaign\imperial_campaign.
I have included backup files for your convenience.
This should work with plain old retrofit, but I haven't tried it and cannot guarantee it.
Enjoy!
I have posted a new version with Random Attack's faction standings fix and Xeryx's new and improved Battle AI.
