Nah, this isn't accurate at all. They might have more heavy hitter, blockbuster type games now, but that's not really automatically a good thing. Thats almost all they make now. That, and shitty GaaS games.
Their software and second party deals might have been for less blockbuster titles back during PS1 and PS2, but there was a steady stream of quality games.

This list includes a lot of weird stuff like CoD being a Sony published game in Japan, but the list is very thorough. You can notice a distinct pattern of less and less games as time goes on. And then you get to PS5 and it falls off a cliff.

2021: shitty GaaS Destruction,

Garbage. I bolded all of the good new IP's for you.
They rely waaaaaaaay more on third party now than ever before. Nothing wrong with relying on third party, they earned being the cool casual console. And every publisher is releasing less games now than they did back then because games cost a lot more to make. But their software output is a dumpster fire.
