COD3/World at War/MW1/Black Ops didn't run well on Wii, but they still sold over a million a piece.

I'm playing the devil's advocate here I know, but I don't think COD has any chance of even running on the Switch. And let's face it, most other modern (PS4/XB1) triple-A, realistic graphics games can't either. Sports games are significantly less demanding, so they can run cleanly.

Doom/Wolfenstein are an exception because their engine (ID Tech) is probably the most scaleable engine in the industry (allowing Doom to run on a potato). ID software are outright wizards when it comes to their tech, and are very experienced veterans in game development (though I'm not trying taking any credit away from the Switch itself to be able to rum those games, as you have to remember, that this is a handheld as much as it is a home console).

BO2 and Ghosts ran well on the WiiU and sold like shit.

Because the Wii U itself sold like shit.

So you are encouraging developers to put out a sub-bar product to earn a quick a buck? That's exactly how we got WWE 2K18 on Switch.

You can port a PS4/Xbone game to Switch without it being WWE 2K18 levels of awful. Doom, Wolfenstein II, Outlast II for instance are of acceptable quality despite the necessary technical cutbacks.

COD is one of the biggest franchises ever. It should not sell that bad on any console. It even sold like 1.7M on the Vita. COD has been in decline on Nintendo consoles since COD 3 on the Wii.

The Switch audience is not the same audience as the Wii and Wii U.

No, but the COD community is.

Switch and Wii U audience are the same.
