Either one of those would make more sense, if you want to have a Perso-Turkic culture. Though I would personally just use the Mughals.An alternative could be to have the Uzbeks led by Muhammad Shaybani in lieu of a syncretic Transoxianan civilization, as I had done so in previous lists. Or maybe just have a Timurid civilization and be done at that.
I guess if you are going for indigenous civs I'd go with someone from the southern part like the Guarini or the Mapuche again, since you have the northern part covered with the Muisca.Take off the Tatars for the Manchu. Cut out Bohemia for a South American civ (Guarani or Cambeba/Omagua?).
I'd like a civ from modern-day Nigeria too, but I can agree that giving them 4 out of 9 possible slots, almost half, for Sub-Saharan Africa might be too much.I hardly ever play with TSL (takes the fun out of exploration) and so this wasn't for me a big priority. I believe the civilizations centred in modern Nigeria are ethno-linguistically diverse enough to justify simultaneous inclusion?
Not sure which is the fourth civ in Anatolia: Byzantium, Ottomans, Hittites and ?
