Define third party controller.

I have my Steel Battalion controller, which was required for the game. Best controller and gaming experience I have ever had. Worth every penny.

But does that count as a third party controller, especially since it can only play one game?

Regarding controllers that are more generic, I have found 8bitdo's Pro+ pretty good, but I am not fond of the joystick placement. I had an Xbox One knock off controller that had the layout of a WiiU Pro controller and I loved that, but it was wired only and that was disappointing. I had a Wii Classic controller that was styled like a WiiU Pro controller and I liked that too, but it was only a Wii classic controller, and couldnt be used on basically anything other than the Wii (the vapor console Coleco Chameleon used images of it for its controller).
