One game controller to rule them all? Not yet, but the Backbone Pro sets out on that path and covers a fair bit of ground -- for a nontrivial $170 price tag (thank you tariffs) plus an optional subscription at $40 a year to bring the necessary features into play.

Not only can the Backbone Pro connect to tablets, VR headsets and more via Bluetooth, but the Backbone app now has a retro gaming emulator

Backbone's Pro Controller adds a pair of remappable back buttons, upgraded analog sticks, Bluetooth, and a bunch of customization features.
