This Kirby: Nightmare in Dream Land interview was originally featured in Nintendo Dream in 11/2002 (a truncated version was also published online at NOM). The questions are lighthearted and fawning, but it's fun to see the team joke around as they explain the various design choices behind Kirby's first GBA outing. Note: I've edited the interview down a little bit from it's original size (there were a few opening SSMB questions and some more personal info about the devs; both sections might be worth adding at a future date).
