The Morrígan AI

Post by KimberlyAzula »

Good day everyone!
This is a post to introduce and share an AI that is very dear and near to me. It has been in development since early October 2020. I (Kimberly Azula) am not actually the scripter, it's CheeseOnToast. But I am the one who decides what is fine to add and what not and what strategies seem "realistic" and old school enough for this AI. And I am the one who came up with the idea and yeah. Anyways, more to that later.

General Features:
- Only plays the Celtic, the Roman and the Mongol civilization
- Micromanagement for some units
- Is up-to-date and will be kept that way
- Is not a competitive AI, only written for fun and to have my random strategies from years ago implemented into an AI


Why did we create this AI?
The Morrígan AI is basically the manifestation of my playstyle from years and years ago when the HD version of aoe2 was just released and I played a few ranked matches. Back then I had only ever played against the old AI. And I only ever used a few strategies.
And I always loved the Celtic mythology and love the idea behind the Morrígan. CheeseOnToast offered his help and we began working on this AI. I mostly did testing - a lot of testing actually.
The other reason of why this AI came to be was, that I never saw many pros play the Celts which made me quite sad. And I was sick of seeing all those boring archer-rushes and archer-micro as well as scout-rushes basically every single game. Which by the way my AI does not do.


What is the story of "The Morrígan"?
The story behind Her, or rather behind the Celtic Tribe fighting in Her name, is, that one of the female druids who is very close to the Morrígan received a vision from Her, foreseeing the victory in an upcoming battle. The vision was then found to be true, as they won the bloody conflict.
And the druid then prophesized, that as long as they would worship the Morrígan and kept asking Her for assistance, they would win any battle and every skirmish that would fall upon them.
How could their tribe ever lose, if the Goddess Herself always foresees their victory? How can they ever lose heart, how can they ever be defeated by their foes? How can the Morrígan's prophecies and visions ever be wrong?

How strong is the AI?
Again, this is not really a competitive AI, but I would argue it is pretty okay on the arabia map. It can beat the DE AI on the extreme difficulty (with very rare exceptions). It loses against basically every AI other than good old petersen on water maps. It can have difficulties on land maps other than arabia. In teamgames it also underperforms compared to 1 vs 1.

Haha, hi lolasik :D
Somehow you are everywhere I am as well lol. Nice to see a familiar face from the Stronghold Crusader community here as well :)
And yeah, Udwin had made a stream a long time ago about this AI, but it was very early in development back then..
It actually kind of still is..

Oh wow this looks great. And exciting news. Been missing me some good CoT scripting.

And cool to know that you're getting creative, Kimberly :D

I am excited to try it out.

Thank you :D !
And well, is it creativity if you create an AI that just plays like you did (with some slight tweaks) years and years ago?
Have fun trying out the Morrígan :D
