It's funny you say that. Because of that racism, the inclusion of east-asian inspired characters basically proves how non-racist the game actually is.The whole "they are South East Asian not black people" becomes hilarious when you realize that racism is very prominent from Chinese, Korean and Japanese people against South East Asians. To the point that a running (kinda politically incorrect joke) joke is that South East Asians are Asia's black people and Mexicans.
I don't understand these Twitter warriors sometimes. Like when they complained about Kingdom Come Deliverance being nothing but white people in 15th century Bolivia or whatever fucking white ass nation that game was set in. Or the Witcher being Fantasy Medieval Poland-town.
Randomly stick PoC's into games like that is called Tokenism and last i checked nobody liked that shit either.
