This is a post to introduce and share an AI that I worked on completely on my own. It has been in development since the definitive edition was released. It's a very oldstyle script, very weak.
Some pics:
General Features:
- Can play on most standard land maps, but almost exclusively tested on Arabia, Black Forest, Runestones and Lombardia. Can "theoretically" play water maps, but actually only team islands and continental (and maps like continental)
- Can definitely not play maps with a nomadic start or where you have to use transport ships with villagers
- Has a very small strategy variance, which in 1 vs 1 consists of no more than two different strategies, but in teamgames the variance is greater
- Can play all civilizations released so far
- Can play standard victory and conquest victory
- Can play diplomacy (with it's own little idea of what diplomacy means, this script is used by multiple of my AIs and was created by CheeseOnToast)
- No DUC
- Is up-to-date and will be kept that way, probably, hopefully
- Uses most "normal" AI behaviour
- Does not avoid TC, tower or castle fire with units
- Is generally pretty chill - but unlike the current DE-version petersen, the AI does not go for a FC
- Is not a competitive AI, only written for fun and to have my own version of a petersen-esque AI

- Unique player names (all female because petersen mostly uses male names and I don't like that)
Why did I create this AI?
Chill AI was created because I love the standard aoe2 AI, petersen (AI (CD version)). I love how chill it usually is, how it mixes the units, that it builds walls and a lot of other stuff. So, here is my version of it, with my own little tweaks and preferences implemented.
I also wanted an AI that is fun to play against and brings back the feeling of a campaign AI.
How strong is the AI?
Again, this is not really a competitive AI. It can beat the AI (CD version) aka petersen, but can't beat any other standard AI integrated into the game. Did not test much at all against other scripter's AIs. I am happy with it though.
Current problems:
-Economy needs adjustments
-Unit composition
