They all have the same problem and that problem is money. They want more of it.
Incorrect; the CEOs want more of it so they can line their pockets. Shareholders may want more to increase their investment but not if it comes at the risk of the product they bough stocks in. Hence why you had Goldman-Sachs investors questioning SIE on the PC strategy at an investor's call earlier this year.
Y'all really like leaving that part out :/
As costs continue to rise and other platforms become more attractive, the temptation to release on multiple platforms becomes too great.
Costs only continue to rise because of inflation and creative choices in AAA game dev. Only one of those is outside the control of publishers, can you guess which one?
We already see 60% of PlayStations resources are going day and date to PC.
For their GAAS titles. And it's a bad bet on SIE's front; they had lightning in a bottle with Helldivers. Instead that attention has been split up into games like Concord, which will likely fail commercially, leaving less room to fully capitalize on stuff like HD2.
Also, just because a company is doing a certain strategy, doesn't mean it's a smart strategy. See: Microsoft's moves for Xbox consoles over the past 10 years. And, yes, that includes Day 1 Steam for all of their 1P titles (which mainly started happening THIS generation).
We already see a number of their big single player exclusives come to PC after a short time.
And outside of an even smaller portion of them, not exactly setting the sales charts on fire.
Nintendo won't sit idly by as its costs continue to rise. Will Switch 2 marketshare rise at the same rates as Switch 2 budgets? Not likely.
It doesn't have to. Nintendo's one of the most stable companies in the world when it comes to finances, and they haven't been overtaken by greedy dumb shareholders or questionable CEOs. You have this extremely flawed idea that all companies are the exact same, and will chase money to the absolute ends of the earth, their corporate identity, ethos, or culture be damned.
That is simply not the case. Just because you've been hoodwinked by Microsoft and the GAAS market at large, doesn't mean other gaming companies operate in the exact same fashion. It's time you start looking at these companies for what they are instead of what you think they are.
Games are the platform, not plastic boxes.
They are both the platforms. And if those plastic boxes didn't matter, why haven't SIE or Nintendo made their hardware tech open-license for anyone to use to build their own systems? Why hasn't Apple with their iPhones? Google with their phones? Samsung? Even Microsoft hasn't done this (yet) with Xbox hardware.
Once again, reality smacks your farcical fantasy in its face.
