If this is to be believed than I think Nintendo would need an exclusive fps series like Turok had been in the N64 days. It should NOT be like Turok, mind you. Just a regular soulless fps. It wouldn't even matter who develops it. Just make it brown and grey and have some guns. More is not needed.
Also, they would need a generic sandbox game. Doesn't even have to be very creative. Just let a generic character run around in a city and wreak havoc while accidentally fulfilling missions.
Also, they would need another action-rpg like Skyrim, just with a typical copypasted sci-fi look or a cookiecut fantasy setting with a typical morale system where your actions and answers to random characters seems to influence your development but in the end all strings lead to the same result anyway.
All of these need to have the exact same "art style", of course. They would go well with Wolfenstein II and Doom on one hand but you also must remember that a steady flow of more NBA 2Ks and WWE 2Ks comes as a side dish, too. No more FIFA is going to come, though. EA probably won't be satisfied with FIFA 18's sales, no matter how good the numbers turn out to be. But anyway, this should still be enough to make some kids who believe they are adults go have a look into the Switch.
