Not just Chinese, I think most eastern countries use their own languages. Be it Japanese, Korean, South-eastern countries, or whatever. Reasons might include English isn't their official language, or hasn't been included in mandatory subject and what-not. And I think China market alone is big enough to sustain itself, though I remain doubtful. Another thing to consider is their highly competitive environment which drives cost of living so hiring a translator wouldn't be efficient solution for an indie developer still. But that's just my speculation.

There are too many variables to consider. There is some collaboration between the East and the West when it comes to things like this but mostly, it has to do with the laws governing each country. If we take away the fact that China's gaming industry is still developing, the propaganda inherent to such games, copyright conflicts, controlled media (what goes in and out of country), China's need to maintain their historical accuracy in depiction of historical figures (afraid people would butcher the game and the Chinese government wouldn't be able to stop it), lack of interest in hiring translators to cater to an international audience or even have need of it since China already is a major baseline for sales and therefore catered specifically to the Chinese without regard to international reception (not that the minuscule attempts they tried had any success), I could go on and on about different issues but mainly, it's government and lack of interest in the West with regards to Chinese games.

Living corpse is literally human tho. And It certainly can give concent, lol

Why would they ban it? Steam allows "sexually explicit games"
Because she looks underage or what? XD
