A lot of older PC games can run just fine on modern phone hardware. I’d buy a SteamOS version of a phone that has some modular or built-in set of buttons and analog sticks. I don’t know how the app ecosystem would work for sensitive things like banking but it’s mostly a minor issue for me.
By real games i mean pc games. There are plenty of various open source lauchers or third party android ports from github which can run real pc games on android. But the problem remains: either bad performance, as the game is not optimised for mobile hardware, or terrible touchscreen controls, as the pc games might require a lot of keys to play.
For example, i can play minecraft java edition on android using zalith launcher, but some medium modpacks may not work due to lack of memory or unsupported mods, and playing it using touchscreen is very difficult. Unlike some other games, minecraft java edition isnt really designed about controllers, and even with dedicated mods which add support for them, arent really useful.
