Board game the Chinese players the option to download their account data before shutting down the servers. Whoever did that will (presumably) have the option to upload that data once the services are restored.
Extremely unlikely, Blizzard probably don’t want a bunch of files that have been tempered with. Also, if it’s like the data export you can also do for non-Chinese accounts, it’s just stuff like transaction history, chats, and essentially your profile in a game like Overwatch (match history, stats, etc.).
Afaik neither blizzard or netease saved any of the data. Blizzard didn’t because Chinese players’ data can’t be stored on servers outside of china and netease didn’t because…fuck 'em?
I’ve read the exact opposite. When the servers went down Netease (or Blizzard) announced the accounts would stay and be saved.
~250 games testet, about 90% worked without issue.
Some games were hard coded to avoid Intel graphics and would use the AMD iGPU by default (even a newer title like Alan Wake 2 did this), but after disabling the iGPU, most of those were fine.
I think like 10-15 games didn’t work at all or had basically unplayable performance, maybe a few more with graphical glitches, some minor, some more noticeable.
