Nintendo could embrace what they do best which is creating hardware. I have a plethora of different controllers including a steam deck and my OG switch pro controller is still the best one.
My favourite console of all time is the "new" 3ds XL. They need to lean into the retro gaming wave that is happening rn.
My modded new 3ds xl has a broken top screen after a recent trip and it is almost impossible to repair. Parts not available. If they just made a good handheld again I would buy.
