Today Sony officially announced their revamped version of PlayStation Plus, which will offer various tiers and new features, like a catalog of classic titles and cloud gaming. That said, there’s one thing that’s not included in Sony’s Xbox Game Pass competitor – new release first-party titles. While Microsoft adds all their games, including big ones like Halo Infinite, to Game Pass on Day 1, Sony will continue to hold back. In a new interview with GamesIndustry.biz, PlayStation boss Jim Ryan made it clear it simply wouldn’t be feasible to keep creating major blockbusters like God of War Ragnarok and Horizon Forbidden West if they were offered on PS Plus right from the get-go.

[In terms of] putting our own games into this service, or any of our services, upon their release... as you well know, this is not a road that we've gone down in the past. And it's not a road that we're going to go down with this new service. We feel if we were to do that with the games that we make at PlayStation Studios, that virtuous cycle will be broken. The level of investment that we need to make in our studios would not be possible, and we think the knock-on effect on the quality of the games that we make would not be something that gamers want.
