"They had home run after home run. It’s been a steady decline ever since."
It's not that I don't understand your point. I'm hoping we get lots more titles for smaller IP like motorstorm, wipeout, modnation racers etc.
But at the end of the day, commercially, Sony first party has been taken to new heights this past decade.
How many Playstation series had 10m sellers before 2013? Gran Turismo.
Now post-ps4 launch? The Last of Us, Uncharted, Horizon, God of War, Ghost of Tsushima, Spiderman.
They've had 3 games break their fastest ever selling game record in the past 2 years.
I do hope we start to see a more diverse lineup of smaller titles but Sony's releases over the last several years have been phenomenally successful.
Sony are doing what they're doing because it sells.
