I haven't seen enough, I don't know these devs and haven't read any impressions on it. Just saw a few trailers, so I can't make a proper prediction.
But for what I saw, I think it may deserve 85-89%, but anti-PS and and anti-China sentiment of some reviewers will drop it to 80-84% or so. Or who knows if even 75-79%.
I voted 80-84%.
Is this the 1st big Chinese AAA?
Nah, there's Genshin Impact, ZZZ, Honor of Kings / Arena of Valor or Naraka Bladepoint to name a handful of them.
These are the ones developed in China, someone could also count the many games developed in the west by studios owned by (or published by) Chinese publishers like Tencent or Netease.
There's also many games not published on console (PC and/or mobile) or not even published in the west that could qualify as AAA games, if we understand them as games with budgets of aprox. over a hundred millions dollars or so.
We also have to consider that a huge portion of the devs who worked on western and Japanese AAA games (Sony, MS, Ubi, Take 2, Capcom, Square...) are from Asian outsourcing studios, many of them from China or nearby countries, who also work in these Chinese titles.
