In the latest EDGE magazine (September 2018, issue 322), FromSoftware CEO Hidetaka Miyazaki revealed that he has no preference whatsoever between working on a game based on a new IP or a sequel based on existing IP, as both are ultimately equally compelling to him.

Personally, I have no preference. That largely comes down to the business decision in the end – to what everyone wants to do. Personally I think both have their merits. A brand-new IP like Sekiro allows me and the team a lot more creative freedom to try new ideas. But a sequel is equally as fun because it allows me to refine existing ideas, to improve things that I maybe regretted doing not so well the first time around. As both a creator and a player, there’s this level of creativity that means both are on equal ground.
