Much of the regurgitation of content in Zelda, particularly with locations, characters and music, is related to the series’ huge nostalgic appeal. Zelda would not be Zelda if it didn’t have that main theme tune, right? Or if the master sword went unmentioned, or if the pointy-eared, green tunic-wearing hero never turned up for the event. As a huge fan, would you accept a Zelda game without these things?
This is one of the most difficult things that a developer of an on-going series can face. Zelda is undoubtedly one of -the- classics, so any major change could spell disaster. All I ask is that they don’t force the player to use even more of the Wii motion system.
