Yakuza Like a Dragon is going into the experimental territory as it changes the 3D brawler everyone knows and loves into a turn-based RPG akin to the Dragon Quest series. It's quite an overhaul and understandably the most daring reinvention of developer Ryu Ga Gotaku Studio. They even have a new protagonist Ichiban Kasuga, who is taking over the reins from the beloved Dragon of Dojima Kazuma Kiryu.
Yakuza Like a Dragon cross save
Yakuza Like a Dragon does support cross save, but only on the Xbox Series X|S version, the PlayStation 5 version does not support cross saves between the PS4 and PS5. This means that if you play on the PlayStation 4 version that releases simultaneously to the Xbox and PC, when the PS5 version releases in March, you will not be able to carry on your save file.
With the Smart Delivery program Xbox, your save is completely fine in Yakuza Like a Dragon; it'll still be there if you play it on the Xbox One, then decided to purchase an Xbox Series X|S later. It's fully transferable.
With the PlayStation, from what we can gather, when you load up Yakuza Like a Dragon on the PlayStation 5, you'll have the option to either choose the PS4 or PS5 version to play. If you choose the PlayStation 4 version, your save file will still be available for you to carry on but without the next-generation enhancements. If you play the PS5 version, your save won't be there though you'll have the next-gen improvements.
Basically, you should still be able to keep the save data but won't be able to use it in the full PS5 next-gen version; you'll only be able to use it with the PS4 version playing in backward compatibility mode.
Yakuza Like a Dragon cross-gen
There will be cross-generation improvements for Yakuza Like a Dragon; however, not much information has been released, though we know for certain that 4K, 60 FPS, and faster-loading times are a given with next-generation technology. As Yakuza Like a Dragon has no multiplayer, cross-generation does not matter in that regard.
With next-generation consoles, we know many developers aim for 4K and 60FPS simultaneously, though Yakuza 7 is one of those games that you have to choose either or in, as it'll have three modes to choose from - Normal, High Resolution, and High Frame-Rate.
Normal is the best choice for the most smooth experience, as it caps the resolution at 1440p 60fps, and you'll very rarely get frame drops.
High Resolution makes the game 4K but halves the frame-rate down to 30 fps, though, every other Yakuza game has been 30fps apart from Kiwami, Kiwami 2, so it might not bother you. And of course, High-Frame-Rate where the resolution is capped at 1080p, but the frame-rate will never drop below 60fps.
Even Sega is having a laugh with next-generation technology - check out the video below because well, who doesn't want next-gen crustacean AI in every game ever?
