In that case, I have a quick question. For the GWAM points, is it 50% to the next category for Writers, Artists, AND Musicians per city taken? That's the wording implied by the description. I think most of the functions of that UA exist somewhere in the code, but I'm not sure.
That's exactly what you described : pineappledan suggested that we should keep a bonus of the original civilization for alternate leaders (so that some core mechanics are preserved), so that's why I try to do.
This GWAM bonus is exactly the one possessed by Napoleon in the Esprit de Corps UA.
Also, do you have any further thoughts on my ideas for Venice and Carthage?
For Venice, I'm still unconvinced that another UA is necessary to make the civ a potent warmonger. For the seconday flavor of a 'faith/warmonger' leader, the problem I have is that I have no good idea that isn't fundementaly op... I'm still thinking...
As for Hannibal, all the interest of this leader will be contained in his unique promotion, but once again it is difficult to establish for now (let's not forget we began thinking about his only yesterday : time will bring ideas).
Any idea on these fronts, @pineappledan ?
For my money, the Greece alternate with Alexander seems like the easiest one to cut your teeth on. There's lots of resources with the Greek split by Pouakai, and pretty much everything suggested can be done with SQL, except for the trigger for "leveling up" your GG.
To me, Louis XIV's two bonus seem much simpler (one part is even used in vanilla Civ V, although this version is boosted to take all types of yields into account, so I don't know if a copy-paste is possible), but I'm not a coder, so you're the captain, captain.
