Not exactly on topic, but depending on the phone hardware, GameNative may allow to run PC games. I think, it’s worth mentioning because hardware becomes more performant, and emulation support improves over time, and I didn’t expect to be able to play something from Steam on my phone, and yet recently I started doing just that (in my case it’s Slay the Princess, the game is great, but doesn’t fit the bill of what you’re looking for)
