Square Enix's PS5 through the system's backward compatibility feature.
FF7 Remake was announced during Sony's conference at E3 2015. Square Enix might have announced the game a little early, as fans had to wait until 2020 before they got their hands on it. The initial presentation said that fans would play it first on PlayStation, which was later revealed to be a one-year timed exclusivity deal on the PS4. The box art for Final Fantasy 7 Remake even had a sticker confirming the exclusivity, which likely pleased the PS4 owners around the world, as they were the only ones able to play the game in 2020.
Square Enix is a third-party developer/publisher and it's likely to release FF7 Remake as a multi-platform game in the future. FF7 Remake is a far too high-profile to stay locked on one system, and it's likely going to make a lot of money when it finally comes to PC and Xbox. The question that Final Fantasy fans have been asking is: when is Final Fantasy 7 Remake actually free to come to other platforms?
FF7 Remake: When PS4 Exclusivity Ends
The timed PS4 exclusivity for FF7 Remake was pushed back when FF7R was delayed by a month. FF7 Remake was released on April 10, 2020. As such, the timed exclusivity will end on April 10, 2021. It's unlikely that the deal will be extended any further, and it's also unclear if the sequel to Final Fantasy 7 Remake will have a similar deal on the PS5, as it's still in development.
Square Enix almost certainly has more versions of FF7 Remake in the works. The question is when Square Enix will be able to announce them, as it's possible that the timed exclusivity deal also includes announcements regarding other versions of the game. It's possible that Square Enix will have an announcement ready to drop on April 11, or even a shadow-drop on other platforms.
FF7 Remake will almost certainly come to PC, Xbox One, and Xbox Series X/S. It's also possible that it will come to Nintendo Switch as a cloud game, in the same way that Control: Ultimate Edition is playable on the system. Fans of Final Fantasy games on other platforms likely won't have to wait long to enjoy Cloud's latest adventure on another system.
The PS4 exclusivity deal for Final Fantasy 7 Remake ends on April 10, 2021.
