So. I have 2 I hate.
I had this old gamesube one for the switch. It was a wired one by powerA. Buttons would get jammed, accidentally broke the stick by leaving it in a bad position overnight (my bad) the cover of the cstick randomly slid off (had to glue it) and the while thing was hollow.
Also, I have a keapster explorer and the dpad is awful. Sometimes it jams to the left but its just a plain bad dpad, no physical feedback at all
The very worst controller I’ve ever used was this no-name joystick in the 90s. You had to grip like a claw, which looked kind of cool and futuristic but was awful in use. The base was tiny and it had these suction cups that didn’t work at all.
But the very very worst thing about it, was that the input was binary! It was either on or off, no gradual movements or anything. Basically it was an oversized d-pad.
I borrowed it from a friend so I could try Rebel Assault, which looked so awesome what with CD-ROMs being a new thing. But that joystick ruined the experience so much! Try flying a ship through a canyon when all you can do is hard turns in 8 different directions. I constantly crashed within the first 10 seconds of the game and kept thinking it was my fault for being a crap player.
I still hate that monstrosity with every fiber of my being.
Flashbacks! This reminds me of my first Gravis Gamepad (IIRC). Was a disappointing joystick, even compared to old Intellivision controllers.
It was okay with fighting games, and I do recall a nineties PC giant robot fighting game (One Must Fall maybe?)
Still, my first joystick that I actually loved and made a game much better was an old CH Products flightstick. Early flightstick, so it only added a throttle to the base, so no rudder control.
I remember playing Comanche Maximum Overkill with that stick and just popping in and out of canyons. Also Earthsiege and Strike Force Centauri. I ended up with a Saitek Flightstick, and it was even better (Independence War is a fond memory) but the difference was not as revolutionary as going from a regular joystick to that first CH Products flightstick.
