TL;DR: Final Fantasy VII Rebirth is just $39.99 on Amazon for Prime Day, a 43% mark down from its $69.99 list price.

One of the big complaints about the PlayStation 5 has been a lack of compelling exclusives, so you should cherish the ones that do exist. While Final Fantasy VII Rebirth isn't technically an exclusive anymore (it's on PC now), a PS5 is still the only console that can play it, and anyone with even a passing interest in Final Fantasy, RPGs, or open-world games should consider checking it out for 43% off.
Picking up from the conclusion of 2020's Final Fantasy VII Remake, Rebirth tells an expanded version of the original 1997 game's middle third. Cloud, Aerith, Tifa, and the rest of the gang set off on an adventure around the planet featuring a decent number of huge, varied open-world maps with a massive variety of things to do in them. It's also got what I called a "best-in-class" combat system in my review, cleverly blending real-time action with some elements of turn-based tactics.
Did I mention you can easily spend more than 100 hours playing this game if you want to do everything? For just $39.99, it's a heck of a value.
