I disagree with game prices increasing and I disagree that we have to pay to upgrade when PC users get it for free.
I also believe something like this should be like a Platinum Classic price when Remastered with so little done.
But... I don't think a freebie tied to your account regardless if at Sony's choice you still have access to it even when not subscribed equals the right to a free upgrade.
I do think it would be nice if Sony automatically upgraded PS+ Collections to the latest version.
But I don't think it's an entitlement.
That's for people that bought the game, which you did but sold it because you got the freebie.
I would never entertain doing that
But you still need the disc....
