This varies from map to map, but generally the civs which have strong early game are the most dangerous. Since the AI also does 0 micro, the unit dps is the dominating factor here, which means we are looking at a civ which can combine jav + swords. This makes Romans the top of the list. Spartans and Gauls are also strong.  Normally the AI shouldn't be allowed to reach late game, but if it does, the civ with the best champions win. Elephant civs are probably the best? Then Macedonians and Iberians have the best champion lineup. 

This is terrible advice if you really are starting from zero; and I'm pretty certain you are. Otherwise you would have a look at some of the other mods out there and quickly realize there is no coding needed for what it looks like you want to do. You want to change how units in the game look. That's art assets. You can edit them with art programs like MS paint. You want to change the names and stats of units. That's simulation data. You can edit it with text editor programs like notepad (if you hate yourself). If you give it enough context, ChatGPT can very accurately talk you though performing all of these steps, from navigating to the right folders, to teaching you how to edit the files, to guiding your modifications, to getting better tools that will make the process much less tedious. Just remember that with a low profile project like 0 AD, ChatGPT doesn't have perfect knowledge. It needs you to be its eyes: double checking that its hazy impressions and impulses conform to reality and common sense. It's basically an alien life form magically conjured out of all the data on the internet. It has to interpret and navigate all its interactions with you though its hazy memories of that origin point, plus a miraculous feat of brute force intuitive inference. And it can also teach how to code, faster and better than any other method except hiring a full time private tutor. The key is to never ask it to code for you. Ask it to teach you how to write your own code; and more vitally, ask it to teach you the basic skills and knowledge to continue learning of your own initiative. That will take you far.

I was thinking about something more "gangsta", hence he mention of Tupac.

As per title, which civilization is the most dangerous in the hands of an AI? I've noticed Persians can be tough later in the game when they start training chariots and elephants. Which civilizations gave you the most trouble?

I don't know whether you consider Sugarhill Gang Rap or Hip Hop, but as far as I'm aware their Rapper's Delight was the first hit from that corner; and I wouldn't consider that song overly socio-political. So I wouldn't agree with that simple timeline.   How about folk rock in the anti-war movement in the US?   You are free to say that. Though that notion wouldn't find much support.

I imagine this could be something that matches your criteria and that is hip hop 

It's true — in fact, I don't believe that an artist's aesthetic research necessarily has to be cerebral or experimental. I believe that an artist should simply use it as a means to express the emotions or concepts behind a piece, rather than delegating all the communicative power to the lyrics. This process, generally, can be carried out without creating anything too “weird” to listen to. It all depends on the subject of your activism, and what you want to express about it. For example, imagine you want to write a song about civil disobedience. Aesthetically speaking, expressing anger and violence certainly doesn't require any particularly elaborate musical tricks. For example:  On the other hand, if you want to talk about more complex topics, the aesthetic boundaries (at least the mainstream ones) of music must be pushed in order to fully express extreme emotions and concepts. The classic example is the attempt to write a song about war. An artist can choose to write absolute garbage like Mad World by Gary Jules, turning the madness of war into a crying little tune that might as well be about a failed romantic relationship; or they can attempt to express that madness through the music itself. It goes without saying that in such an attempt, the common aesthetic sense must be left behind — because the violence of war does not fall within common aesthetic norms. It therefore becomes necessary to break out of conventional frameworks if one wants to speak credibly about something like that. For example: Or: Music is art, and when some "music" is clearly not art then it is clearly not music as well: it becomes a commodity. Of course there's nothing criminal in enjoying consumer music, but as listeners we have at least to know what are we consuming. I am free to eat McDonald's, but I am not free to say McDonald's is a top class full of nutrients meal. Also I don't believe that a high degree of musical education is needed in order to appreciate complex music, assuming you are talking about technical knowledge like music theory, harmony etc. The only thing needed is curiosity! I'm barely able to read a staff, for example, but I can enjoy a lot of contemporary classical music. It's more about ideas than technicalities! About the original subversiveness of rap, I think both of those aspects were already true for rock/blues music.
