Again, the empire was Turkish, not Albanian, Bosnian, Greek, etc. It was centered on Turkey, ruled from Istanbul, the main language was Turkish. And when it fell apart it turned into the modern state of Turkey, because this is what it basically was: Turkey + conquered lands.
Easy. We focus on the people, not the political entities. Like with the Uzbeks, there were a few Uzbek states in history, there were Uzbek leaders, such as Muhammad Shayboniy. There is no need to go to Tamerlan and create a Timurid civ.
It is like calling the Russians "Romanovs" (or "Soviets"), or the English "Tudors" or "Stuarts". The Ottoman Empire was an episode of Turkish history, albeit a very long one.
You are confusing the terms "Turkic" and "Turkish".
There are not such struggle. The many possibilities are there but there are not real difficulty into just pick some of them with a defined design criteria.
Leaders have many design elements attached to them still others are civ (proper) based, so pigeonhole leaders from Classical to Atomic, from very different regions, languages, religions and thematic focus to the common elements of an unified contemporary based India waste a lot of personality and uniques that each one of those cultures could enjoy going as solo civs. Talking about five alter leaders for the same civ likely would lead to some mingy designs.
Even in the historical base entities like the Chola empire were not realy triying "to be India" neither their legacy is linked only to the contemporary India.
Then we have things like Scottish civ that not only is now part GB/UK but even many of their in-game design elements come from the period already under English dominance.
About Indian players, AoE2 splited off their already in-game Indian civ and the Indian players loved it.
How do you imagine classical Persia, Egypt and then suddenly Ghandi? Or Canada in ancient time anyway.
Consistency is precisely one of the main reasons to have multiple civs from the Indian subcontinent. Yes, because those "Indian" empires are not just contemporary India but Pakistan, SriLanka and Bangladesh history.
6 Chinese? Maybe not 6 proper Chinese but things like Jurchen and Miao civs are as valid as Gauls or Cree civs (of course Tibet is a popular option but Firaxis would not dare to mess with chinese goverment).
5 Greek? Since CIV6s multi-leader Greece + Macedonia + Byzantium + a Greek leader for base Egypt is not enough, right?!
The others could justify some when those are like the options for "India" from very different eras, cultures, religions and thematics. For example Nusantara could easily provide a Dharmic Javanese civ + a Muslim Malay civ. Or the also elephant in the room classical Zoroastrian vs modern Muslim Iranian civs that are as unique as Byzantium is to Rome and Greece.
I just wanted to admit you both made good points.
To be honest the main reason why I would like to see Timurid civ is uncomplicated, I'd just really like to see Tamerlane, his empire and Samarkand (Central Asia) at its prime, and I try to find some way to justify them being in game. We could have "Uzbek" civ centered around Shaybanids but let's be honest, they were simply infinitely less spectacular and influential on the global scale than Tamerlane. That's my problem with Central Asia: I want it to shine at its prime in civ series, but its hard to come up with its major representative which isn't some ephemeral multi ethnic political entity. Actually the best era for Central Asia wasn't even Timurids but pre-Mongol conquest era of perpetual political chaos in the region not inhibiting enormously refined culture and economy. It's hard to represent that.
To make matters even more messy, Central Asia was extremely important for Persian culture, Persian language and Islamic science, but you can't really include it under "Persia" or Arabic caliphates.
As for India ok you are maybe right, I wouldn't like to decide about it myself as there are too many possible options of dealing with India in civ7.
