I don’t know if it would make sense for them to ever make Dark Souls 4 since Elden Ring is the more popular franchise and they’re probably going to stick with open world going forward. But I think it would be pretty sweet if they made a remake of Dark Souls with an open world or something.
A prequel to Bloodborne would be amazing. These theories of exploring ancient Pthumerian civilisation in the desert sound so cool. Or a prequel to Sekiro where you play as Tomoe would be really cool too.
