Groove Coaster: Wai Wai Party!!!! devs on why they localized the game, and how Undertale tracks came to be included

Many were surprised to see that Groove Coaster: Wai Wai Party!!!! was getting localized, myself included. Wondering how it all came to be? Siliconera talked to Producer Takuma Hanagata to find out.

We’ve had a lot of players requesting a console version of the Groove Coaster series on Twitter and Facebook and as the smartphone, arcade and Steam versions were all released internationally, we had an international release in our sights when we began planning for the Nintendo Switch version.

Another big surprise came from seeing Undertale tracks added to the game as paid DLC. Hanagata explained how that came to be as well.

We received a lot of requests on Twitter etc from fans of the arcade and smartphone versions wanting us to include it, but popularity alone wasn’t the reason we considered adding Undertale; it was because the tracks lend themselves well to a rhythm game. The track choices were influenced by whether we believed we could make a compelling stage from them or not.
