There are plenty of other controllers out there to choose from, but the vast majority of them require you to mount your phone.
That’s where the Razer Kishi ( ~$100 USD) comes into play. In order to make the most of the experience, you’re going to need a good controller.
While cloud gaming doesn’t have me prepared to ditch the console anytime soon, that doesn’t mean I don’t want to at least check it out.
