This achievement intrigued me -- "Win a game against 3 AI at Humankind difficulty on the tiniest map". Welp, my friends, after about a half-dozen Ancient Era curb stompings and one game where I managed to get all the way to the Medieval Era, while both AIs were Industrial, I need some tips. Any secrets to success? Aside from starting near copper, iron, and horses, hoping the AIs aren't aggressive, and lots of luck?

You need to play the long game. Create a 60-70% land map where each player has its own very small continent + an empty new world for you to rush to. Depending on your game speed you may be better off multiplying exponentially as a nomadic tribe for a spell while the AI is limited to a slower ancient era unit spawn (useful if one AI somehow gets on your continent, you can swarm them and capture a new city).

Then again, there are multiple tactics you may pick and RNG could be on your side eventually..

Beware that it might be bugged. The opposite achievement is (the one that requires you to win on the largest map against 9 AI at highest difficulty). I did, and the achievement did not trigger. It was a long, hard game and the bugged achievement pissed me off, but I kept the save in case it gets fixed in the future. Hopefully.

My bet: out of the 9 AIs, one was a G2G persona (quill nonetheless), and I guess that confused the achievement code... 

yeah this is still the case today, needs a bit more clarity on the description me thinks.

Lord of the Flies achievement does not trigger either... Won as military, Germans in cycle 360, made all 3 AIs vassals and got the King of Kings achievement, but not Lord of the Flies.

Hey guys,

Would you have the saves that didn't trigger the achievements ?

I just tried this today and it still didn't work. My game settings were:

Humankind difficulty

3 AI opponents

Small map 

Normal pace

No mods

Yes I do. How do  I share them?

Hey there,

I've tried both tiniest map against 2 adversaries : https://cloud.owncube.com/s/jSBsJ8szigsEi3k

and small against 3 adversaries : https://cloud.owncube.com/s/nwYKjw9yzEpGGeL

Weirdly, the achievement shows 2 out of 3 on steam.

Hope it helps.

This achievement is still bugged in April 2022, as are Wonder-Full and Price-Cuts. Here is my T200 Space Victory from today which failed to trigger (3AI on small map).

I cant find anything conclusive on this achievement anywhere. Should i play on a tiny or small map? Is the achievement bugged? Can i use G2G ai or no? I vassalized 3 AI on small map without achievement trigger so answers appriciated :) 

According to the achievement you need to play on a tiny map, not small.
The type of AI should not matter as long as the difficulty is set on Humankind.
