Only two primary buttons feels pretty limiting
I know plenty of games can exist with only two buttons, but it’s still limiting and likely to be off putting to many devs.
Made me wonder whether we're observing some variation of Hotelling's Law [1] in controller design.
PS: the episode mostly is about Panic's upcoming handheld game console Play Date [2] which also has two primary buttons (and a crank!).
