Independent install for me. There is an option where you can enable additional languages aside from whatever you picked on install, both for written stuff and for verbal dialog. Having more than 1 language will probably mean downloading additional files though. Not sure how much is involved. The game is currently sitting at 41 GB on my computer.

I figure if I want to know what the CN version sounds/reads like, there's tons of playthroughs on bilibili I can browse.
