You cannot assume that almost any of your players will have a controller. So you have to design for the crap little diving board thing that it came with, which is very limited for what games could do with it. And that's it. It wasn't enough that it was possible for people to buy controllers. Since every Apple TV didn't come with a controller, effectively zero of Apple TV's market would have one.
