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.
I would personally love to see another game in the style of Bloodborne. Maybe not a direct sequel but a different project in the same universe. That game was the pinnacle of Soulsborne games for me.
