While its story and cinematic moments are great, much like the previous FF7 Remake, it has its few problems.
Camera: First, the annoying camera wasn't improved at all. Like in Remake, the camera does not clip into walls and instead zooms in when it collides against walls, which could lead to horrible angles, especially in tight spaces. This is applicable to both free roaming and combat.
Controls: The control scheme that they have established in the first game does not translate well into the open-world type environment Rebirth introduces. You cannot freely jump, instead you have to constantly guess which terrain can be climbed on. While sprinting with chocobos, you will undoubtedly get interrupted by obstacles and uneven terrain, most apparent in the Gongaga region. To make this worse, navigating the region is horrible. You cannot have both tracker and minimap active in the UI and there's no waypoint system of any sort (unless you count chocobo sniffing but not really).
That said, it's still an enjoyable game. I'm only halfway through and I've already spent 70 hours, thanks to all the numerous side quests and minigames distracting me from the main story lol. But I hope they improve what I've mentioned above in the next installment.
