As I said on the top line.
I have X-wing Alliance for mod purposes to play, but no joystick, yet. That's my next purchase. It requires one to work properly, so I figured why not get more games I can play this way. Seeing that steam prevents you from using some games without their bullshit, I wanted some they don't hold your dick hostage to play.
I recommend Vampire Survivors & 20 Minutes Till Dawn. Both are $3, on Steam, and you can probably remove the Steam folder and have them just work. Usable with joystick too.
They are both roguelike games, with a progression system.
