I got hooked on Civ 6 recently. There are some things that are a definite improvement over earlier entries. The Chinese unique unit is now the Crouching Tiger, an actual historical Ming Dynasty weapon, instead of the old fictional chu-ko-nu. Qin Shihuang also speaks in classical Chinese, which was a very nice touch.
Unfortunately the series is still heavily Western centric. The description of the eras are based on European culture. Fully half of the playable civilizations are European, or of European culture. The civics are the worst offenders: there's a civic called colonialism!
Policies like serfdom and colonial offices are fine, because you can choose not to use them. A civic, however, is part of the tech tree and you have to get them. This is a real slap in the face to those cultures who have suffered from the depredations of European colonialism.
Colonialism also allows you to declare colonial warfare, which results in lesser warmonger penalties. This is an amusing though perhaps unintended reflection of Western culture's lack of concern over their own warmongering.
Finally, it looks like Mao Zedong is not going to be in Civ 6 at all. The new Rulers of China pack features Yongle, another version of Qin Shihuang, and Wu Zetian.
Personally, I miss leading China to world domination as Chairman Mao.
