You should look into just how restrictive Chinese Steam is. You should also look into how any online game operating in China (like PUBG) needs to be offered by a joint-venture with a Chinese firm.
Let us not forget the revolutionary idea to-- now pay attention cause this is BIG-- to prioritize player experience! Can't believe nobody has thought of that before.
I wonder how much of that is marketing. That eats up most of a AAA game budget and I don't think it was heavily advertised outside of China (where it had a big marketing campaign)
