Finally, let's hope they implement it to all their previous PC games.
Let's hope they also implement cross-save too, to unify our progress in both platforms via cloud saves.
They already are the top grossing company in console gaming, and this will is another step that will help them become the top grossing publisher on PC too.
It's an important step to end releasing their own PC launcher and PC PSN store, hopefully somewhere soon and featuring crossbuy with console for games available in both platforms.
They did learn from it, and this is why Sony does not include their games day one on their subscription and only releases the non-GaaS after having being sold some years only on PS, once game sales on console already dried out.
As a result, Sony's strategy is super successful and their console business is more successful than ever and keeps growing increasing their market share, while Xbox is dying and keeps losing market share.
Yes, this is an important step.
