The Backbone One would be an ideal game controller—if the iPhone had more games
In theory, it ought to be as good a time as ever to be a gamer on the iPhone.
Classic console emulators have rolled out to the platform for the first time, and they work great. There are strong libraries of non-skeezy mobile games on Apple Arcade and Netflix Games, streaming via Xbox and PlayStation services is continuing apace, and there are even a few AAA console games now running natively on the platform, like Assassin's Creed and Resident Evil titles.
Some of those games need a traditional, dual-stick game controller to work well, though, and Apple bafflingly offers no first-party solution for this.
