There is no perfect controller…

…But I do have a list of features I would want my perfect controller to have based off all the controllers that have ever been made :

• TMR joystick modules (successor to Hall effect sticks)
• adjustable tension springs and locking mechanism for varied stick cap types
• 6 DOF / gyro sensors + infrared camera (Wii Motion Plus)
• Adaptive haptic triggers (PS5) which can be toggled to hair trigger mode via switches (Xbox Elite series 2)
• multi-touchpad on face (PS5)
• analog face buttons (DualShock 2 controller used this for the Metal Gear games) with customizable “per-button” color assignment / micro OLED or e-ink screens so button graphics can be swapped
• USB-C / 4 wired connectivity + charging
• baseplate contact-charging (PS5 controller has these so you can set them on charging docks)
• hot swappable battery pack + AA battery holder pack or ability to not have a battery on at all when connected via USB-C (Xbox 360 controller had this)
• swappable non-magnetic Zinc-alloy faceplates (PBTails new controller has these)
• removable back triggers with dedicated button assignments (like the Steam Deck’s L4/5 and R4/5 buttons; not just cloned face buttons like Sony and XBox do)
• integrated microphone with hardware toggle (PS5)
• proper “separate keys” d-pad… not the mushy type
• touch-sensitive surfaces for every button and stick (Meta / Oculus Quest controllers do this)
• per-finger-joint touch sensitive grips for each finger segment (Valve’s VR controllers did this)
• the ability to separate the halves of the controller so that each hand could hold one half independently and have them track similar to most standard VR controllers (think combining the switch controllers and Quest controllers)
• NFC communication (Amiibo-stuff for example)

If any single controller did even half of this, they’d easily be the GOAT.
