Arent they digital CODES? In that case it means they dont have anymore codes to give out.

mostly hardcore nintendo fans bought the WIIU, there  no question in my mind that most double dipped for a superior portable version on switch, especially with how limited the game line up was, aside from zelda, what else are they gonna buy for the next 7 months?

But I don't understand how they can run out of codes to give out? I don't get it lol.

Nah I don't buy thay for a second. I think as you stated the Wii U was mostly Nintendo fans. If you look at Nintendos own data the Switch is being bought by a whole different group of people. Which makes sense. MK8D might have been bought for the reasons you stated but it's not because the majority of wii u owners bought a Switch and that they bought a second copy.

Smash 4 did ~14 million, yes its on 2 platforms but thats irrelevent, you dont segregate the sales of cross-gen/multiplatform games.

If somebody asks you how much FIFA 18 or COD: WWII sold, you would say over 15m and over 18m. You wouldnt just take the sales of a single sku to determine its sales.

The codes are assigned to cards given out by Sony, Amazon doesnt just make up a random code to give out.

You point out something telling it's silly, only to follow up with something that's even far more silly. GoW selling 10 million is certainly possible with the hype if the sales ain't very frontloaded, but for Smash doing less than that it must be a totally broken failure to achieve such low numbers On a console with adequate sales numbers like the Switch.

As for 3D Mario vs Animal Crossing: AC is generally the bigger seller, because apart from 64, Galaxy and now Odyssey, they really don't sell that well. 7.5M for Galaxy 2, 6M for Sunshine, 5 for 3D World. And all of them had bundles (especially Galaxy, Sunshine and 64) helping their numbers even further. The real sellers are the 2D Marios, which normally sell about 3 times as well as the 3D ones.

That said, Odyssey is an obvious masterpiece and selling appropriately. It will, without a doubt, outsell any other 3D Mario by a country mile, considering the best-selling one is 64 with 11.9M sales (Maybe even as soon as the IR Meeting  next week). While AC is bigger, it's just slightly so. It will get tough to beat Odyssey for Animal crossing

who knows, but i think most mario kart fans that owned it on wiiu would love a portable version. 

how is selling on 2 platforms irrelevant? now thats its down to 1 platform?

Yeah, on the Wii, which many "core gamers" missed out, who are considered the main audience of the franchise. And a pretty contested sequel to Melee to boot. And yet it sold over 13M

3DS Smash alone could quite possibly break those 10M this year too. A game considered a hallmark of competitive action gameplay sells 10M on a pure handheld who doesn't have that kind of audience. Just think about the implications and then think again about Smash on Switch sales. You could say less than 10M this year, which is quite possible especially if it would launch in December, but LT sales of less than 10M are just ludicrous.

laughable. how many games have broken over 5 million for animal crossing? only 2 in the past 18 years. Lets look at every entry in both franchises. its not even close, 3d mario is much bigger.

mario 64 11.9 million

mario 64 ds 11.09 million

mario sunshine 6.31 million

mario galaxy 12.7 million

mario galaxy 2 7.7 million

mario 3d land 11.7 million

mario 3d world 5.75 million

mario odyssey probably 18 million ltd. 

animal crossing.
