Any game. It’s a remote desktop app, basically. If it’s a steam game, it will come with a default phone touchscreen gamepad set up and usually there are also official and community layouts you can use. The layouts are… not as good as you might like, and I am frequently having issues with my custom ones disappearing or not loading. But it’s not the worst thing ever and I can play modded skyrim on my phone at work.
Non-steam games can be added to the steam library and you can manage their controller schemes the same way- sometimes they will even have community layouts available also. MMV with non-steam games. For example, Valorant won’t recognize my mouse click on my phone. And certain apps apparently force you into a “local input only” mode and might kinda break your setup until you play around with it a bit (don’t go into task manager lol).
But yes, you can also easily connect a bluetooth controller to your phone and any game that uses a controller works great.

I’m not playing the victim, I’m pointing out why your rhetoric is counterproductive and bad optics. If you want actual change to occur, you’re going to have to fix that. Or you can just keep making things worse, if you really want to. Go for it. It’s really worked out for you well so far, hasn’t it?

iPhone users are out of luck afaik but you can try your mileage with android if you have it.

Bro couldn’t finish the prologue because their attention span is 10 minutes and somehow thinks the game has more cutscenes than content.
