As I understand it, if I pop in my Uncharted 4 disc and buy the PS5 upgrade, it gives me PS5 copies of both Uncharted 4 and LL. So I guess it could be rationalized as either a $5 upgrade for each or a $10 upgrade and a free game if you only have one of them?
I got the impression that it's $10 to upgrade each of them. It's not worded very well.
"PlayStation Plus members who claimed Uncharted 4: A Thief’s End via their PlayStation Plus subscription are not eligible for the $10/€10 digital PS5 upgrade."
This is really dumb. Sony is screwing up the upgrade path. Microsoft is destroying them in this area. Charging $10 is bad enough but for them to not allow this version of the game to be upgraded if you choose is another ridiculous choice.
