That's because Nintendo is the largest publisher and developer for their own platforms, so they get to reap almost all of the rewards when their consoles are huge hits like the Game Boy line, DS, Wii, and Switch. And why they were still able to manage and profit just fine during their consoles that struggled, underwhelmed or even flopped like the 3DS, GameCube, or Wii U. And the BIG reason for that is they understand the importance of variety.

Not every game has to be a AAA blockbuster juggernaut that has to sell a gazillion copies to break even. You can have a healthy serving of B-C tier appetizers in between the A-S tier main courses, in fact, you NEED to have those in order to make the whole meal 5 stars. If Nintendo just stuck to 3D Mario, Mario Kart, Zelda, Pokemon, and Smash Bros, that would make for a VERY dry 1st party lineup and their consoles would really struggle to sell. So they make sure they have a healthy supply of games like Kirby, Fire Emblem, Donkey Kong, Yoshi, multiple Mario spinoffs, Metroid, Pikmin, and Xenoblade Chronicles to hold over the audience in between those major releases. And those games sell consistently well enough in addition to their megatons to where they don't even have to consider releasing their games on other platforms to break even. Not only do the games sell very well, but they do so while staying at their full MSRP price for pretty much their entire shelf-life - Which sucks for us as a consumer because deals on Nintendo games are so few and far between. But it works to Nintendo's big advantage because they don't have to lean on sales and price cuts to move the units they're aiming for and they make a lot more money off of 5 million copies sold at $60 as opposed to 1.5 million at $60, 2 million at $40, and another 1.5 million at $10-20.
What also helps considerably is the fact the Switch, from Day 1 or very close to it, has sold at a profit. So, they don't have to lean on strong software sales to make back the money they'd lose on hardware sales from selling their system at a loss like Sony and Microsoft do.

Speaking of Sony and Microsoft, in addition to the "selling hardware at a loss" problem I just mentioned, They have had a terrible habit, since the tail end of the PS3/360 era, I wanna say, of "Go Big or Go Home" with their 1st party offerings. When you look at Sony's first party offerings, and with the exception of probably Astro Bot, all of their releases have been these massive, grand-scale games with HUGE budgets attached to them: Horizon, Spider-Man, God of War, Ghost of Tsushima, Last of Us. A shit-ton of money has gone into making these games from production values, development costs, marketing, etc. That they kind of HAVE to sell huge numbers to make a decent profit off of them. And with no smaller releases to fill the gaps, they pretty much lean on 3rd parties to do that. Problem with that is, they don't get to reap nearly the same number of rewards in software sales because they have to split publisher fees with the 3rd party devs as opposed to taking it all for themselves like Nintendo usually does. 

And as hardware gets more and more expensive and the budgets get higher and the money coming in is not keeping up, THAT'S why they have to eventually release their own first party games on other platforms. Sony is starting to do it and Microsoft especially is being hit hard by it, as evidenced by the declining Series S/X sales, because now the consumers know they don't have to get the Xbox version right away, they can just wait for the PC, PlayStation, or Nintendo version and get it there. And unless Sony takes a couple pages out of Nintendo's playbook that I mentioned earlier, they're gonna run into the same problem.

Your example of a 3rd party game skipping ps4 because Sony wants more ps5 sales is ridiculous. First of all, it's a 3rd party games. Sony's not dictating if it has to be on ps4 or ps5. This comes down to the developer or publisher of said game. If you were right about Sony being worried about people not buying ps5s, they wouldn't have spent the first 2 years releasing their own 1st party games on ps4. Not to mention games release on the ps4 all the time, and will continue to in 2025. 

I'm not going to address your other arguments because they are as asinine as this point. 

All you do is shift your arguments around to make whatever point you are trying to make to defend Sony. Anyone who spends any amount of time reading your comments understands this. 

i guess you could say Microsoft is experiencing an Xbox 360.

I think you mean 180 since they are going in a different direction. 360 would be staying course lol

Whilst it may technically be a third party game, Sony and Pocketpair entered into a partnership before it's release on PS5. It makes no sense why they put it on Xbone but not on PS4. PS4 sold twice as much as Xbone did and it's more powerful too. I believe part of the deal of their partnership was to not release it on PS4 to help with PS5 sales. There is no way of proving this theory, but again why release it on Xbone but not PS4?

They are a small indie developer. It would have taken longer to get a ps4 and ps5 port out instead of only ps5 since it's the platform they started development on after they released the PC and Xbox versions. The partnership is with Sony Music Entertainment for merchandising. It is about making non-video game products like toys. It has nothing to do with Playstation. The game was announced in 2021 so they likely started development on the Xbox One and then ported it to the Series X/S. 

You have failed to understand the industry that's the problem. As much as you love beating from your chest Xbox is dying, this is a term we have been hearing since the XB1 era. How many times can Xbox die? How many times are they going to die in 2025? Because I am afraid to tell you that there is going to be another Xbox, so something isn't adding up, you don't continue making hardware if the hardware isn't selling... or maybe Xbox console goals isn't to outsell Sony or Nintendo, maybe it's just there to provide an option. MS are most likely not producing that many Series S/X machines in the first place.

Let me educate you on this industry. This isn't the 90s and early 2000s anymore. The industry is evolving day by day. Unlike the past, where the only way to sell software was on a dedicated device, this day and age, there are a plethora of options that no longer require a plastic box to access the games. 

As much as you want to deny the facts here, Xbox is building for the future, they are better placed than both Sony and Nintendo in the all-digital future, they own the gaming Cloud Network in Azure which Sony uses, they own the biggest operating system in the world, they own the biggest Publisher in ABK, they have the biggest gaming service in GamePass, sure they are not selling as well as Sony in the living room, that's where it ends. 

The Popular saying goes "What doesn't kill you, makes you stronger." Xbox make money on PS consoles with ABK and Bethesda games. Indiana Jones (Licensed Game) and Doom (Legacy Game) are of no Suprise they are multiplat either.

My question to you is, if Sony is doing so well, Why are they releasing games on PC and Switch? Why are companies like Square pulling out from Deals with Sony to go Multiplatform?

The Xbone and PS4 architecture is almost identical so it would require barely any time and resources porting it over from Xbone to PS4. With them being a small developer it actually makes much more sense to have it on PS4 because it's extra money. There is no good reason for it to not be on PS4.  

360 could also mean they did a little spin, got dizzy, and stumbled into a wall...though 180 is more what i was going for lol. So, I guess Microsoft did an Xbox 180 during the 360 (ironically).

One reason is the extra money would be tiny. They probably saw how little the Xbox One version sold and didn't bother. Also you're forgetting that it's not just the time and resources for the port, it's also future time and resources with continuing to update that version and making sure it keeps working well by doing things like testing out any major updates on it before releasing them. It makes complete sense why they'd not wanna add a PS4 version to their workload for miniscule benefit.
