Against hope, I would prefer if both were included because SE Asia is one region that really deserves to be as densely populated as Europe.
I couldn't agree with this more!
Speaking of which, it occurred to me that I should share what I voted on as well!
My first pick for Southeast Asia and Asia as a whole is
Burma. It was the largest Southeast Asian empire and once ruled almost the entire region under Bayinnaung. Even when it didn't it was still quite a powerhouse.
Next is
Vietnam, the popular choice on these forums for understandable reasons. Most if not all of its history has been spent rebelling against other powerful states and it is the part of Southeast Asia that's been more influenced by China rather than India. How they didn't make it into Rise and Fall is beyond me!
I agree that the
Timurids would be a great option for TSL, notable leaders, great influence, etc. I also kinda sorta definitely forgot to include the Mughals in this despite how cool I think they are (though I think they'd probably be an alternate leader for India so I won't worry about adding them unless its suggested more on here) but I think the Timurids are a better choice regardless.
Judah would be a great choice for just how influential it has been for religion and Hezekiah would be an interesting leader to see. Modern Israel could be controversial but I don't see why ancient Judah should be.
Tibet is another one of those civs that I've grown to love the more I've heard and read up about them. It really is a huge shame with how sensitive the Chinese government is otherwise this would easily be one top tier choices for brand new civ from any region let alone Asia. While Tibet is an undoubtedly worthy choice, I'd like to mention why I'm interested in
Bhutan. It seems like a very odd choice given that it's a smaller nation but Bhutan is a better choice as a stand-in for Tibet than Nepal is. Bhutan was formerly a part of Tibet until it became it's own kingdom in the 1600s and managed to defeat invading Tibetan armies a few times. Bhutan also has a lot of Tibetan influence in its culture and architecture not to mention the shared Buddhism. Nepal is neat in it's own right but it's also much more heavily influenced by India and Hinduism.
Other shout outs:
Yakutia: No offense to Canada but I was hoping that Yakutia would be the tundra farming civ in Gathering Storm. They had settlements in the extreme cold of Siberia and Tygyn Darkhan had created quite a kingdom/empire for himself.
Akkad: We could use more ancient era civilizations and Sargon would be a very cool leader to have. If Firaxis really wanted just 1 Mesopotamian civ then it would've been the Akkadian empire with all the cities of Sumeria, Assyria, and Babylonia in its city list to leave no room for doubt.
Philippines: A pretty distinct culture that has plenty of pre-Spanish history to draw from.
Yemen: The Arabian peninsula could use more love and a female Islamic leader would be quite different.
Hephthalites: I probably wouldn't vote for them over most of the other choices here and the Timurids are pretty much superior in every way but I do want to say that they sounded pretty cool in that Kings and Generals video and they did have settlements so they at least had that over the European Huns (sorry Attila).
