I investigated the apks of pc games floating around and found it actually pretty easy to play some major pc games on mobile. I'd go to fmhy.net to find trusted sites but the one from there I use for android apks is APKVISION.org. I grabbed hollow knight, silk song, blasphemous, dead cells and gta SA from there. So far I've installed silksong, dead cells and blasphemous on 3 different phones and they worked fine. I recommend the mod versions with built in cheats, which does require special app permission to display the cheat menu over top of the game. Of course your phone specs will determine how well they run but you can adjust the resolution and effects levels in most of these games. A modern dimensity or snapdragon is best, with at least 4gb ram and above. I have not installed GTA SA so far so can't comment on fully 3d games yet. I don't plan on consistently gaming on my phones outside of a mobile console while traveling or bored out and about etc Motorola modern phones have been using either the dimensity 6300 or the snapdragon 4 gen 1 which of either works fine on silksong, deadcells etc More RAM helps of course. A backup cricket phone the icon 6 I got for $9 struggles at native resolutions for both games, you have to turn it down, lock it to 30 etc The Icon 6 uses a very budget low end cpu, not sure about the gpu there. Any mid range phone should work fine.
