Thanks for all the replies, sorry I didn't reply to every one but I read them all, keep them coming please!
I am glad to hear joysticks are still popular in some circles.
Some more random thoughts:
I mostly play 4X games or other casual games nowadays where mouse and keyboard suffices or is better suited. The most recent time I spent significant time with a gamepad is Zelda OoT on an emulator. I can probably play that with a joystick I think, but some of its mini-game might need finer control with an analog stick.
Aside from fighting games, I can imagine playing 2D shooters with a joystick. Metroidvania games too, but some of them have functions assigned to so many buttons I'm not sure a joystick has enough.
