This is why I played K1 before 0. I'd rather play a so-so game with potential for improvement than an incredible game with a big drop in quality afterwards. Story wise K1 is fantastic. It's just lacking in a lot of QoL. Plus I loved the Majima Everywhere gimmick.I played 0 after 6, and honestly there's so many call-backs and references that I wouldn't have understood at all if I'd played it first
