It's been a year since I uploaded the last official AIV Multi-pack, so I thought I'd upload a small treat for everyone.
These AI castles are small enough, for the most part, to use on all those confined, pretty maps that you have been no doubt creating and not sharing ;-)
Again, these are made to emulate each AI character's personality and to be a bit more durable and productive. Don't expect ANY AIV file to turn an AI character into a tactical genius. The truth is that the AI profiles are simple, and they are each designed to fill only niche role in the game.
No matter how great of a castle one makes for the AI, it's just not going to resolve some of the major issues with the games logic. The AI will still do stupid things on a regular bases. To name a few AI quirks that will probably never be addressed; The AI accidentally sealing its castle exits, grouping its siege forces way, way too close to enemy walls and towers prior to attack, and constantly trying to build on resource piles right next to enemy forces.
