Nintendo Puzzle Collection is a compilation of three classic Nintendo created puzzle titles that were released in a single disc for the GameCube. Despite being developed by Washington based developer Nintendo Software Technology (note: the game was co-developed by Intelligent Systems), the game was released exclusively in Japan and not in America or Europe. The three games that were included are Yoshi's Cookie, Panel de Pon, and Dr. Mario 64. The two latter games were enhanced, though Dr. Mario 64 remained the same as its Nintendo 64 incarnation, which was never released to Japanese audiences. In the game, Dr. Mario 64 was known simply as Dr. Mario, perhaps not to suggest that the game was actually intended for the Nintendo 64 instead of the GameCube.
