Mmm, that would actually be very silly.
It's not that different civs are too similar to be in the same game, it's that they basically ARE in the game already. Siam gets to build the wat, but it was the Khmer dynasty who were really the wat builders.
A wat isn't a particular style - it's simply a word meaning "temple" (strictly, it translates as 'school' because the temples acted as monasteries), and is of neither Thai nor Khmer origin. Arguing that the two countries overlap because of their shared word for temple is like arguing that you shouldn't have more than SE Asian civ because all these countries have guesthouses called "Same Same But Different". A temple like Angkor Wat plainly differs architecturally from one like Wat Phra Si Sanphet. Angkor Wat, the most famous Khmer monument, was constructed as a Hindu temple, and the Suryavarman II (the Khmer leader in Civ IV, and builder of Angkor Wat) was Hindu. By the Sukothai period the Khmer and Thais were Buddhist. The two groups are ethnically distinct.
So, you have differences in culture, architecture, religion and ethnicity, simply to start with, that you don't find between neighbouring European civs like English and French to any degree (save to some extent for religion).
I think that for a game made in America it is actually very good for not over shadowing the game with European influence. The Mali and Songhai can't be in a game together, that would just be silly. That's like having America in the game, and then having American in the game again with Obama as leader calling it "America Later On"
There was a period when the two were contemporary (albeit briefly, much more so than Sukothai and the Khmer), but since civs like Sumer and Babylon have been together in past incarnations of the game (or the Iroquois and America in the current version and Civ III), this isn't a good reason to bar Mali and the Songhai from being in the same game. The Songhai came to power in northern Mali, but were ultimately derived from a Sudanese lineage.
European being highly overrepresented is just a awful thing . But since "Into the Renaissence" scenario seems that it'll be the biggest scenario ever built,then their idea or overrepresenting Europe to represent some areas seems fair enough . At least,I hope they throw other European Civilizations in Freeze and release them in a second expansion or as a dlc post-2nd expansion,except if they release a double pack with a European civ and a non-european civ .
It's overrepresented, but it's hardly an "awful thing". The only difference with Civ IV at this point is that we have Austria instead of the HRE and Sweden instead of Portugal. The reason there are fewer civs from Africa than there were last time with an equal number of civs isn't because of European civs, it's because Polynesia represents a region Civ has never visited.
I'm also looking forward to the scenario - more themed scenarios with their civs added to the main game would get my vote. And a Renaissance scenario sounds fun.
If Tibet was in the game I would switch over from maining Mongolia to maining Tibet, especially if the leader page had a golden budhaa in it or something, units that had a "Meditate" ability instead of fortification, that would be crazy cool.
If Tibet was in the game it wouldn't (at least shouldn't) be the modern plateau culture best-known for peaceful protests, monks setting fire to themselves and a wise leader in exile, it would be the aggressive, empire-building theocracy that once conquered and controlled China and much of Southeast Asia and which was commonly the aggressor in frequent wars with China (most recently declaring war on China in 1932).
14 / 34 = 43% - Fourty-three percent of all civilizations in the game are European.
Land area of Europe = 6.3% Land area of Earth
Population of Europe = 10% Global population
They are horribly over-represented, and this can be seen by playing a TSL Earth Map
Could be worse - look at Empire Total War. Single player campaigns aside, 10 of 12 (83.3%) factions are European despite a theatre of war that extends to Asia (both West Africa and India), North Africa and the Americas (where there are no indigenous factions in multiplayer games).
