But for all the countries the price for regional priced games goes up when the value of the currency increases.
The price of a regionally-priced game remains the same, regardless of currency exchange rates. No Man's Sky, for instance, still costs €60 after this local price update. The only thing that changes is the amount of store credit you receive. When the currency goes up, you get more credit and when the currency goes down, you get less.
The only thing that goes up is the equivalent price in $, which might or might not be kinda better than the current exchange rate.
