So ports like GoW 3?
They need to learn from Microsoft that they should add more content in the remasters. If they don't add new content why the fuck are they making us pay 40 bucks for a game that looks pretty much the same on an older console for 20$?
Because nobody wants to pay for PlayStation Now on top of PS+.
EDIT: This is pretty much the crux of the issue. They want to push PS+ instead of true BC. If they have true BC then PS+ will be useless, and they can't milk consumers with single game remasters like GOW3.
