It's really useful on steam when you can add games to your wishlist and see when they are on sale and stuff. Even outside of the sale, just having a wishlist is nice. Is there a way to access some kind of wishlist on the PS4 store. I saw that there is a wishlist on the web store on the mobile app. Is there a way to view these games through the P34?
No, there is no wishlist on the PS4 store. It is incredibly stupid that there is not. The PS Store does a pretty poor job at selling you games in the first place. I hate ads but I would like if the store would start suggesting games to me based on what I already own. Either way, no wishlist for the store just yet.
If you are looking for a PS4 game wishlist like steam, I'd suggest using https://psprices.com/ . It works a lot like the wishlist on steam. You add games to your wishlist and get notified when the game goes on sale.
