You should look over CvRhyes.cpp, that's where all the arrays for the strings for DCNs, UPs, UHVs are stored. Even if you don't have UPs and such yet, Israel for example should have TXT_KEY_UP_ISR, it just looks nicer.
I started as Athens:
- They talk chinese
- There's wine on Athen's starting plot. And a city founding in Ionia (should have been Edessa or Smyrna) was named Athens.
- All the old religions were messed up; Egypt founded Canaanite, Phoenicia Mesopotamian and Babylon Egyptian Polytheism. To solve this, you could make found Canaanite with to the tech following Sailing, and only Phoenicia starting with Sailing f.e.
- I find it a lost chance that you made the map a plain square; the old map with the spherical shape gave the whole mod a nice unique style.
When i didn't have my own mod yet, i tried to work on this one, but quitted it halfway through. The first thing i tried was to give include more techs and buildings, there are tons of mods and scenarios out there where you can get, let's call it inspiration, PIE's Ancient Europe f.e., where you could easily just copy-paste the techtree and building list to have something to start with. Don't forget to give credit where credit is due though if you follow this.
I had some ideas that never made it, because it never got out the not-yet-presentable stage. Some UHVs, some UPs, but most of all i wanted to make the religion system into "culture" groups (Graeco-Roman, Egyptian etc.) and the corporations into the (monotheistic) religions. The catch would be that switching to a different "culture" would have changed you city-style (think of the transition from Pharaonic to Ptolemaic Egypt or celtic Gallia to celto-roman Gallia f.e.). I found that this is pretty easily codeable
