As said, this is about future first party games. The new policy doesn’t have immadiate effect on current developed games. The signal I get is, if true, then new Sony first party games will be locked to their console without porting it to PC. Multiplayer games will be an exception to this apparently.

And for story heavy titles - youtube playthroughs exist as well as blogs and wikis.

This is for me a non option, regardless of what game it is. I either play it or don’t. If the game is a movie rather than a videogame, then I am not interested into it anyway. Watching a playthrough or video on YouTube (or any other service) is absolutely something I would not do (and never done) for this kind of thing.
