You know what, I think you put into words how I feel about this better than I could.The never-ending cycle of reincarnation linking the fates of people across generations is the most interesting aspect of Zelda lore. Nintendo should absolutely explore the power of re-telling the legend not only in different times but also different places and cultures.
If we're gonna have a Black Zelda, I think the whole game should be steeped in Black culture. Maybe make it based off of certain Sub-Saharan African cultures.
