Why would the Chinese government find it offensive? DE is honest in portraying class struggle and it visualizes the very nightmare which Chinese media keep reminding its citizens about. Such imagery is a staple of Chinese education. Pupils, students, officials are obliged to visit places of national disgrace and defeat, and Revachol fits this imagery perfectly.
China experienced severe trauma in the 19th century. "Look up at the sky, at the dark shapes of Coalition airships hanging there." They lived under such skies.
The Opium Wars were organized by Western countries in the name of freedom and democracy. Even today Western media are not ashamed to claim that it is an "autocratic political system fearful of Western ideas" to blame for the defeat in the Opium wars,
no joke. Western powers turned China into Revachol. So of course, the Communist party is totally fine that the game reminds Chinese youth how it feels to live with no future - 欢迎来到实在界这个大荒漠.
DE portrays that even those who are on a favored side of capitalism are losers. Joyce is rich. But her daughters have no future of their own. Kids of rich parents escape playing into Martinaise pretending that they are underprivileged because this is the only place they feel real (that moment with pseudo-SKULLS reminded me a
speech in Tamera 2011).
As for criticism, DE does not actually criticize communism. It correctly points at the disadvantages of a very specific thing -
war communism. But even Lenin had already postulated that war communism was a desperate measure for desperate times, so there is nothing actually controversial about it. Actually, the Chinese might find the Mazov Revolution having more similarities with the Taiping Revolution than with 1949.
