This NiGHTS interview is actually a compilation of several interviews originally featured in jp game magazines like Sega Saturn Magazine and Famitsu. It goes into some depth about the theme of dreams, character design, and the unique gameplay of NiGHTS. Particularly surprising is the team’s initial resistance to 3D and polygons. Naka also professes some Jim Henson-like aspirations for a character who could appeal to children worldwide.
