Craig Grannell, writing on how Apple could make MFi controller-enabled games more user friendly on iOS:
That’s assuming anyone could find a compatible game in the first place, because Apple oddly broadly ignored controllers in the iTunes Store. You’d think the company would at least flag controller support on game pages (something it does on Apple TV), and also automate an App Store page listing compatible games. Instead, it’s left to third-party sites like Afterpad to pick up the slack, which is baffling.
Today, the MFi ecosystem is fairly mature, with a reasonable range of controllers. (My personal recommendation is the Nimbus, unless you’re desperate for a form-hugging option, in which case grab a Gamevice, in the knowledge it may not fit the next device you buy.) But Apple needs to do more to help.
It is baffling that the iOS App Store still doesn’t display controller support or offer a filter to show games with MFi controller integration. It seems like they’re not taking them too seriously.
