By real games i mean pc games. There are plenty of various open source lauchers 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.
