You're alive Illysia!
Also, good on China! Finally I'll be able to know when should I get that sneaky Antonidas... But in all seriousness I think China is getting all up in the paranoid side of games. But there are two equally outcomes: Blizzard pulling a pressure move on China, or bending over and agreeing to their terms. I know that if I had more money and less common sense I'd be drowning in Overwatch loot crates, and it's perfectly understandable that the Chinese want to put an end to this: it's money that's going to a US-based company, and that's a big no-no for them.
Besides, if they want to keep people from paying exaggerate amounts of money for "loot crates" or "luck packs," they should start looking at themselves: Perfect World has been in business for way longer than Hearthstone/Overwatch has, and it's got a myriadful of packs, crates, boxes, etc... you can buy with real money for the chance to win... absolutely nothing. Perhaps something worth one million coins in game, or if you're lucky a strange piece of equipment. It's laughable. Pot calling kettle, perhaps?
On how it affects PS... no way whatsoever. Think about it, free game, only payment you can do is a donation that gives you no privileges other than to appear in the credits, and nothing to gamble with. What are you going to do, hoard treasure chests? Sell tria for real money?
