Did they, though? I think exclusives predate Sony and even the PS1. They’ve been a part of the console space since basically the inception of the medium. Xbox itself launched with an exclusive “killer app” in Halo. Timed third party exclusivity and exclusive Map Packs were very popular with the 360 when it was on top in the seventh generation as well.
I don’t think Sony has ever made an acquisition of the same scope as Zenimax either in price or in how much of the market was fenced off from a studio they previously had access to. That’s not even going into the Activision deal.
Maybe we can now point to Bungie, but that was still half the price. Most of Sony’s acquisitions over its time were studios that were already de facto developing exclusively for their consoles. Even Insomniac. If you look at their history, Sunset Overdrive is a lone anomaly.
Exclusives suck, but I don’t see them going away as long as consoles and capitalism exist. You’re basically throwing shade at Sony for daring to fund the development of critically and commercially acclaimed games that gave them the reputation of having a quality first party library. Starfield on the other hand was developed as cross platform title until Microsoft paid 7.5 billion to acquire a major publisher. Wasn’t this confirmed this week by the document leaks?
Few complain when Halo is released exclusively because no one is being surprised that those games are now exclusive titles. That isn’t the case with the new Bethesda deal.
