Speaking with Metro GameCentral, Shenmue creator Yu Suzuki revealed that Shenmue III will be much like the first two installments in the series with some new aspects.
I don’t think it’s necessary to change the basics of the gameplay. If I change it too much the existing fans will be very upset. Although I am always making up new ideas and things to add to the game, which can be a problem for my team who are trying to implement these ideas.
At the moment we are trying to keep it to 30% new and the keep the other 70% of the game similar to the original. But the design is constantly changing and I am always coming up with new concepts that we can try to add to the game if there is the opportunity.
