The series creator said that the next instalment would have featured more dialogue from the lead characters.
"The world of Shenmue 1 and 2 expanded outward. So, for example, in the original games, of all the data used for dialogue in the game, the main characters' dialogue was about 20%," he told 1Up.
"The remaining 80% was dialogue by characters other than the two main characters. But Shenmue 3 doesn't expand outward, but inward. A lot of the dialogue is used for the main character and especially dialogue with Shenhua. They talk about a lot of different, deeper things."
Suzuki went on to explain that dialogue would involve preferences and hypothetical questions that the player must answer.
"This is not actually in the game, but as an example to give you an idea of what I mean by deeper dialogue: when Shenhua and Ryo are at home, Shenhua will ask Ryo if he would like to drink tea or coffee and the player will select one or the other," he explained.
"Or, Shenhua will ask Ryo a hypothetical question like: 'There are four animals: a monkey, cat, dog and bird. You are crossing the river but you need to leave one behind. Which one will you leave behind?' And the player has to choose one.
"Shenhua will ask lots and lots of questions like these and the answers will get stored in the game and affect the outcome of the player's relationship with other characters. It's like a personality test. For example, the person who leaves behind the monkey is the type of person who leaves their wife."
Suzuki added that if the game were to happen it would be "very interesting".
Earlier this week it was revealed that free-to-play social title Shenmue World may receive a worldwide release.
