Trying to reasonably predict Nintendo's quality 1st/2nd party exclusive output for Switch. 

Ha! Remember those days when all Nintendo titles had “64” in the title?

That's very true. I'm sure certain games like Mario Maker, or NSMBU were quick throwtogether titles. Perhaps Splatoon 2 as well. But in general full fledged console games take much more time to make than handheld games. But who knows. Maybe, Nintendo will keep a separate studio around to make top-down Zelda games, and maybe those games will be praised to the sky and back again, despite being AA budget titles. I mean, NSMB was definitely one of those games. But this is why, I didn't want to include handheld games too much. It's just too unpredictable on that front.

you would need to count every 1st/2nd party game then.

*quality exclusives. Forgot to add that part. Been a loooooonng day for me. Kinda sleepy. 

Where is the portables games? Mario Kart DS? Mario & Luigi?

I think it's best to work in titles relative to their selling capability for this, I think for each year Switch is it's prime of it's life cycle;

2 new titles from their 10 million+ sellers

2017

Zelda Breath of The Wild

Super Mario Odyssey

2018

Pokemon Let's Go Pikachu & Eevee

Super Smash Brothers Ultimate

2019

Pokemon 2019

Animal Crossing, 2D Mario?

1 new title from their 5 million+ sellers

2017

Splatoon 2

2018

Super Mario Party

2019

Donkey Kong, Tomodachi, Luigi's Mansion 3?

3-2 new titles from their 1 million+ sellers

2017

1-2-Switch

ARMS

Xenoblade Chronicles 2

2018

Kirby Star Allies

Mario Tennis Aces

2019

Yoshi

Fire Emblem Three Houses

Metroid Prime 4, Paper Mario, Mario & Luigi, Pokemon Mystery Dungeon?

+Ports e.g. Mario Kart 8 Deluxe, Tropical Freeze, 3rd Party Nintendo published exclusives e.g. Fire Emblem Warriors, Bayonetta 3

That's another way to take a look at it. Find sales figures for every Nintendo published game over the last 22 years and go from there. But I think exceptions need to be made. I mean, some of the previous Mario Party games were utter trash, despite selling well. 

Edit: If you don't make that thread, I will. Eventually... 

Don't you feel there's a BIG omission here? Tell me, don't you?

Something something about a mask...

True, I consider 10 to be the worst in the series and it still sold 2 million on the Wii U. But Super Mario Party is looking solid enough to be on the lines of Mario Party 8 and DS which sold 8 million+. Not the best in the series but they were safe standard Mario Party games at heart and made effective use of the systems hardware, and released on a platform which sold well.
