In terms of players, I think we're basically like everywhere else. Obviously, there's a massive demand for mobile games because people do a lot of commuting and want something brainless to click on. Many people have a Playstation or Switch at home.
In terms of game-making, I find that a surprisingly large amount of game development happens here and covers several genres and types. Although these games don't wear their HK origins proudly. I used to work for a company that would make games purely aimed for Portuguese audiences like Brazil and would never consider translating them into Chinese, for example.
I've also worked for a HK-based company that brands itself as German... for... no reason? They feel like HK doesn't suggest quality to customers and try to hide their origins. Bit weird.
