While the fourth-generation Apple TV supports a variety of MFi Game Controllers, most games can also still technically be played using the Siri Remote as well. However, in a lot of games you’ll probably find the Siri Remote too small and awkward to use as a game controller — especially in those cases where you’re expected to turn it sideways and use the accelerometer. While you can of course just go out and buy a game controller like the SteelSeries Nimbus, that’s not always an easy expense to justify if you’re just a casual gamer.
Fortunately, there’s another possible option, courtesy of Apple’s Apple TV Remote app. In addition to replacing your Siri Remote for normal Apple TV control and navigation functions, it can also double as a basic game controller. Load up the Remote app on your iPhone, and once you’re in a game, a game controller icon will appear at the top of the screen — tap on this and you’ll be taken into a landscape view with a touchscreen surface on the left and two game controller buttons on the right. While you still won’t get the full button support of a standalone game controller (and it’s not going to cut if for any games that now require game controllers), the larger iPhone still has a much better feel for gaming than the dainty Siri Remote.
