Keep starting your posts with a claim to have spotted a fallacy. The problem is you clearly don't know what your point is. 

I'm saying that Nintendo do not have a broad appeal as I'm looking at the entire gaming market, not just one title and it's sales, which is a laughably simplistic way of viewing a complex market. 

The Xbox 1 has mass appeal. The PS4 has mass appeal. The WiiU does not, because Nintendo does not have mass appeal. 

"OMG BUT X SALES".
Yes, but Nintendo only sell to existing Nintendo fans. They are a small bunch when you consider the large amount of gamers. 

Therefore no matter how "well" MK8 sells, it won't save the console and it'll just be SB for GC all over again. It's Mario, and Mario only appeals to Mario fans. On the grand schemes of things, there just aren't enough of them. The issue is you're getting tied down in pointless details rather than stepping back and seeing the big picture. How can Mario have broad appeal when the console with Mario on barely sells?

>"Nintendo doesn't have broad appeal"

My point it simply that you cannot provide an example of a game that has sold over 9 million copies without broad appeal. There are 68 titles listed in the link below that have sold above 9 million copies, they each have broad appeal in common, but to you, it's only the non-Nintendo titles that do.

So now zero Nintendo titles have broad appeal due to console sales? Would you then say that all Wii titles had broad appeal due to the Wii's success?  And this applies to Gamecube but not Xbox original (despite similar consoles sales) because why exactly?

So there's no number that Mario Kart could sell that would show it to have broad appeal in your eyes? Excellent, that's all I needed to hear.

But if we were to follow your next train of thought, that Mario Kart only appeals to Mario fans, then that actually would show it's broad appeal. Look at Mario game sales, they are amongst the very top-selling games and the definition of broad appeal.

Here's a question to answer your bolded question. Have you bought every game (along with it's correpsonding console) that appealed to you?

Which part of "the same people buy all of Nintendo's titles" don't you get?

When both of those games are being sold to the same people, the total is 9 million. What is Killzone + GT + Uncharted + LBP + Infamous?

Come on son, I know you can do basic math. 

Oh mai gawd are you not reading? I'm talking about the Nintendo franchise, not just one game as that's not big enough to see the entire picture. So, now that that is clear, what say you?

Adding together four franchises now? Lol, compare that to Mario + Pokemon + Mario Kart + Smash Bros. Hell, every Mario Kart game has sold more than any Infamous or Killzone game.

That was one of the most impressive ways to prove someone wrong that I've ever seen.

Dude, what is wrong with you? You have literally completely ignored the first sentence I wrote and fail to understand what I am saying. The people who buy Mario will almost certainly also buy Mario Kart, SB, Pokemon etc. Therefore that isn't 4 games for 4 different audiences. It's four games for the same audience. The same cannot be said about 1st party Sony titles. Come on son, I know you'll get it this time around. 

He proved you wrong. It's time for you to man up and admit it.

Because your first sentence is laughable. The Mario Kart audience is men and women, children and adults, a broad range. For the most part, Sony's games have a much more limited appeal; primarily males aged 14-40.
