It's best to just not engage with Platinum, he's a troll who's apparently only here to downplay a platform he doesn't like.

I literally own and play on the platform you're claiming I don't like. Is going into threads and telling others not to engage with users even allowed in the terms and conditions on this site? You have done that more than once to me and at what point does it become harassment that should be reported

Yikes.

There can always be arguments made about who makes the most revenue vs profit vs market share but the thing that Nintendo has that no one else can compete with is the strength of its intellectual properties. No company on earth can compare to that other than Disney... and even it can only compete due to the acquisitions it's made over the years, like Star Wars and Marvel. Mario has been more recognizable than Mickey Mouse for over 30 years now. Even among Americans.

Third party support is always important, but Nintendo is in a far better position to stand the test of time than Playstation, Valve, or anyone else in the games industry. Why? Because even when it slips up here and there with its hardware, Nintendo has maintained such a high level of quality regarding its key franchises and making its games enjoyable. So far, anyway.

Even if the N64 was CD-based, I'm still unsure if the N64 would be the winner. Third parties were just sick and tired of Nintendo's crap by then in regard to their standards and practices. Yamauchi was a dick back then and they were fed up. Even with the SNES being the market leader, that didn't stop them from supporting the Genesis, which managed to wrestle quite a bit of market share away from Nintendo and be a healthy platform in its own right. So Sony jumping into the frey would have taken even MORE marketshare away from Nintendo and Sony had FAR deeper pockets than either Nintendo or SEGA. What they've been doing the last 10 years with companies like Square Enix and Atlus, they could have just as easily done back then - Throw a crap-ton of money and marketing behind 3rd party games to wrestle them away from Nintendo. And it would've worked. Because as long as those games were on Nintendo, they had a ceiling for as much as they could sell. With Sony's backing, franchises like Metal Gear Solid, Tomb Raider, and Final Fantasy had their own marketing campaigns, spotlight, and much higher potential to reach those levels of sales. Final Fantasy VII outsold every single N64 game except Super Mario 64 because of this and it is considered by many gamers all over the world as THE PS1 game. It was one of the biggest killer apps for the system if not THE killer app. You think Nintendo under Yamauchi was going to let that happen? They would NEVER promote and back that game over their own IPs. Not a chance.

Part of why the N64 sold faster out of the gate than the PS1 was that it was selling for $199 while the PS1 was at $299. That was the main advantage of sticking to cartridges over CDs. But if Nintendo had gone with CDs and knowing how they HATE selling hardware at a loss and prefer to be profitable out of the gate - A CD-based N64... Well it sure as hell wouldn't have been $199, I can tell you that much. ESPECIALLY if it was still 64-bit? The PS1 at $299 in 1995 was sold at a loss! Sony was LOSING money on each PS1 sold to start! So given how Nintendo even to this day, but ESPECIALLY back then, prefers for their hardware to be profitable right out of the gate, it would've made the Saturn - which was selling for $399, look like an affordable option. So that would have been a huge shot in the foot for them back then and possibly made it even easier for Third parties to jump ship to Sony and SEGA.

Mario Kart 8, Super Mario 3D and Yoshi's Wooly World world were very high quality titles but it didn't save the Wii U. Even if Zelda breath of the wild came exclusively to the Wii-U it wouldn't have saved it. Quality first party titles alone cannot save your hardware, and Nintendo is in the hardware business. The Switches success has massively inflated everyone's sense of Nintendo's strength in this industry. When the Switch 2 comes out and it doesn't do anything even close to the OG Switches numbers, people will come back down to earth

Switch 2 will easily sell over 100 mi units

30-35 million in Japan alone is all but guaranteed, Xbox is irrelevant and neither PCs or Sony catches the general gamer. Nintendo has a monopoly in the market, which is some ways extends to the rest o Asia. 40 million+ in Asia is pretty safe bet

Selling 60 million in North America, Europe and ROW will be a breeze for Nintendo. It's the only major handheld in the market and will be like that for a while. I can see an argument of Steam Deck 2, and possibly new Sony and Xbox handhelds getting some market share from Nintendo, but in current states of affairs Switch 2 has absolutely nothing going against it. It will be the 3rd best selling Nintendo system effortlessly

So now it's not just they're the market leader, but that they even have a monopoly on the market? The biggest game of all time GTA6 probably won't be on their platform at launch (never has before), and yet they have a monopoly on the market? 

Consoles need good third party support to help ensure long-term success, even Nintendo's, so I would say no. If I recall, Capcom asked Nintendo to give the Switch 4GB of RAM, and they listened. If Nintendo hadn't listened to them, I don't think they would've gotten as much third party support as they did for the Switch.

On the Japanese Market? They have, well if we ignore Mobile gaming market which is in fact the biggest gaming segment in Japan 

Only about 7 million gamers plays primarily on PCs in Japan, and another 7 mi plays on both PCs and Consoles

That's said PC gaming has grown substantially in the last years, so maybe this can take away some of Switch 2 sales. Still there is no way for Switch 2 selling less than 25 million, 3DS sales are the absolute floor for this console and the odds of it selling above 30 million are really strong
