"Gamepad" as an alias of "game controller" (or vice versa)

gamepad → game controller  
OR  
game controller → gamepad

These tags were all aliased into controller which was the largest of them all:
 
controllers, game controller, video game controller, gamepad
 
joycon and joystick both imply controller now.
 
If there are other specific types of controllers, please let me know to also have them imply controller.  
Never mind, I found a bunch of them.

Playstation controllers are known as “Dualshock”, so I think the former would better be aliased to latter.  
i.e  
playstation controller → dualshock  
ps3 controller → dualshock 3  
ps4 controller and playstation 4 controller → dualshock 4
 
With the latter two implying dualshock tag

Considering how few images are under those tags, wouldn’t it make sense just to alias them all to dualshock controller and have that imply controller?
 
I mean, dualshock 1, 2, and 3 are nearly identical visually.

I think that would work, too

Those are all aliased to dualshock controller now.

Now the dualshock controller have aliases, but somehow doesn’t imply controller tag.  
Also, the controller tag contains implications that are already aliased to dualshock controller (i.e. playstation controller)
