Point-and-click ports
There are a wealth of classic point-and-click adventures that would feel right at home on Switch 2 if this mouse functionality comes to pass. The Switch is already good at hitting those nostalgia notes, and bringing the classic PC adventure scene to life would be a treat.
Monkey Island, Myst, Full Throttle, Day of the Tentacle, Maniac Mansion, and more are ripe for the picking if Nintendo really is packing each Joy-Con with a computer-like mouse. Those are just the classics too; recent point-and-click success stories like Norco, Slay The Princess, and Unpacking would fit the bill too. Really, any game that involves directing a cursor around the screen, like A Little to the Left, could benefit from mouse functionality.
