I wouldn't mind a reboot tbh. It can be like MK9 where something happens that causes time to revert, and the game tells the story of SC1 to SC4 and it includes all characters in the series up to that point. It lets players have their dream match ups while also better telling the story and expanding upon the plot with a better narrative. The story and lore is good but they can definitely tell it better with either a remake of SC1-4 or a reboot. It could be called "Soul Calibur: Burning Souls" or "Soul Calibur: Never-ending Legend"
