The two PS4 dynamic themes dedicated to Final Fantasy X|X-2 HD Remaster have been released in North America and Japan via different means, and today European users can finally get their hands on them as well.
Both themes have been put on sale on the European PSN store, for either €1.99 or £1.69. You can find links for the UK store below:
Square Enix UK also released videos for both themes, which you can see below. Zanarkand is especially pretty, while your mileage may vary on the other one.
