I booted it up recently, and it holds up really well. It hits a perfect balance of narrative and action while largely avoiding repetitive fetch quests and the like. And both of the DLC are excellent - Hearts of Stone has the best plot line in the game while Blood and Wine has the most beautiful locations.
Still has 96% recent and 96% overall positive reviews and an “overwhelmingly positive” overall rating.
I don’t think they’re making much of a dent. The article is pretty unclear though on why Chinese gamers are mad, other than that there was a possible “dodgy translation.”
