Gamasutra - Series Loyalty and Straying from the Path
An interesting piece at Gamasutra last Friday that RPG Codex picked up titled Series Loyalty and Straying from the Path touches on "the common stand that brings a series together" and fan expectations. It's rather console directed but does raise some interesting questions:
Nintendo’s Metroid series changed more considerably when it finally made its way into the foray of 3D on the Gamecube. While past Metroid games had been 2D action platformers using the same viewpoint as its contemporaries, the new Metroid, dubbed Prime by developers Retro Studios, was presented from a first person view, akin to shooters like Quake and Halo.
When the game was first revealed, many long time Metroid fans demanded and explanation for such a drastic shift in the gameplay. Some even declared that Metroid proper was dead, and this new series was nothing more than a shadow of what 3D Metroid could have been.
Retro and Nintendo fired back with a simple explanation: both companies felt that Metroid was not defined by its viewpoint or its graphics. Such changes were only cursory and did not take away from what really made Metroid: a sense of exploration, and isolation. Thematically, the argument was air tight. The series still featured heroine Samus Aran as well as her long time enemies the Space Pirates, and of course the alien metroids. Many still condemned the series, and some outright ignore its current iterations.
