The fact of the matter is if you’re allowed to plug in any peripheral into a game console, you can and will get prolific cheaters in a multiplayer environment.
Maybe only bring in this check if your console is not in offline mode? And please make it cheap to actually get certified.
Regular accessories that don’t alter gameplay can and should always be an option for a user. If a certification process has to happen to use the accessory online, so be it, but I hope this doesn’t hurt the market too much.
Edit: I’m aware that Xim currently uses controller authentication to work and therefore this specific change may not affect it. I wasn’t claiming that this would get rid of Xim, but arguing that a huge reason for this change is to begin the process of cracking down on rampant cheating in online multiplayer games (shooters in particular).
