Dev says Like a Dragon series must keep using its own engine
The Like a Dragon series “absolutely must” continue using its bespoke Dragon Engine, but staff must also learn about alternate options, the series’ technical director says.
In an interview with Japanese publication Type, Ryu Ga Gotoku Studio technical director Yutaka Ita stressed that the Dragon Engine is fundamental to the Like a Dragon series, but that it can’t improve without knowledge of alternatives.
Ita explained how the studio used Unreal Engine instead of its own Dragon Engine to make Yakuza Kiwami, its 2016 remake of the first game in its Yakuza / Like a Dragon series. He noted that doing this let the studio identify areas where the Dragon Engine was lacking.

“We don’t know which direction the game industry and development environment will take in the future. That’s why when we train new employees at Ryu ga Gotoku Studio, we have them learn how to create games using three engines – Dragon Engine, Unreal Engine and Unity.
“By knowing the other two engines, we can make
