France and Franks different. Frank Kingdom is Germanic and France is French. That is what I want to say.
But…that is exactly what I mean… For the first few 100 year the Janissaries were elite Christian Byzantines using swords. Only later were the Jennisaries reformed into the Gunpowder wielding, cloth wearing Turks of the 1600’s as dipicted in your image.
They are the same people just as ottomans are turks.
Not Just Turks thou , Britons,Romans,Turks,Mongols,Chinese,Germans are well known for their millitary achivements troughout history.
Can I take this opportunity to mention Janissarys are missing their hats. You can only get them in the editor

Biggest issue IMO hatless Jannissary is basically unplayable. All the other UU’s laugh at him.
20 years ago the devs though the hat will make them look like kkk members hence removed before releasing.
Yes I remember that, makes no sense anymore now that the models look better among other reasons that arn’t worth getting into.
Hats for Jannisarys the buff Turks really need!
I love Turkish civs and all but c’mon dude, Chinese, Germans or Arabs are just as good.
Also this game isnt historically sccurate
There’s a mod that fixes this, just search for Janissaries with Hats.
Why should players bother for it? It is silly that it is not an official content. I am also up for the Janissary model change with hat by devs.
For my mod I gave the normal Janisarry the hatless sprite and the Elite Jannisarry the hat. It works a treat.
I feel major civs Turks, Persians and Chinese are by far the ones needing a UU after 20 years (Persian Cataphract, Ottoman Great Bombard and Fire Lancer) and better historical depiction in this game (adjusting things to keep overall balance) instead of the smaller, recent civs having the most detail.
It’s been 20 years guys…
Chinese absolutely don’t need buffs. Nerfs if anything
How would you balance turks after giving them a great bombard?
You act as if turks get no buffs or love but I can think of quite a few recently that helped them.
Cav archer buffs.
Light csv line buff.
Gun powder buffs of multiple types.
My. God. I just said it has nothing to do with buff / nerf… Simply to find a new equilibrium.
Do you need new glasses maybe?
So since you want rhe change provide the balance changed necessary to balance it.
Persia do get the Paladin, what it needs is the correct cataphract skin as all the units do. Then It will be perfect. I wouldn’t mind having the Turkish bombard cannon get an imperial upgrade to the Great bombard but if they don’t get it, I won’t mind either. A fire lance could be interesting though. Once again, China seems fine to me but if we could get accurate sprites for the units as well as a propper Chinese castle, that would be brilliant.
I think you either misunderstood the question or missed the point. Introducing new unique units affects the game balance regardless of your motives for doing it. Saying that it’s nothing to do with balance doesn’t change that. You even said yourself that this should be done “adjusting things to keep overall balance”. So the question is, what adjustments would you make?
Given that the aim is apparently not to affect the balance at all, here’s my suggestion for how to implement Great Bombards: change the name of the Artillery tech to Great Bombards, and give Bombard Cannon a different graphic once it’s researched. And that’s it. (But I don’t actually think they should do this.)
See this is not a completely bad idea but I also believe that this is a step in the wrong direction for what makes aoe2 what it is.
Can Great Bombards even be moved without disassembly? Maybe it would make more sense as a unique upgrade to the bombard tower, where it requires villagers to build in the desired position.
What exact adjustments are made to keep balance is not essential, as there are endless possibilities.
In my view, the only essential thing is the Great Bombards should be in any medieval game. That includes AoE 2. Period.
Oh, and Turks and also Persians are big civs in History and should have a proper heavy cav skin at least (balance is not even tweaked).
