“are the PS4 consoles usually modded? Is it difficult to find games in English?”
Google can answer your questions. It’s absolutely not Chengdu specific. Download all of the PS4 torrents you can possibly find.
If you want pirated games, China can take care of your needs – but you’re limited to last-generation consoles. If you want a PS4 and the games that go with it: you’re likely to get English *only* (AFAIK there is no such thing as a Chinese only PS4 game. WTF?) and you’ll have to pay foreign price plus whatever the middle-man who is selling your game to you wants as a cut. Xbox One however, has found an “in” though the shanghai free trade zone to sell consoles more ‘directly’ to consumers, that’s why you’ll see them at, say, Auchan…because consoles were only just legally available in China.
“Available in English”.. yeah.
