Legend of Zelda: Skyward Sword [SPOILERS]

Just beat the game. 32 hours without any side quests really done.

 Spoiler

Although you might think Groose is a good vessle for Ganondorf, it just simply doesn't make sense. Groose loved Zelda, and harbored no hate for Link when he finally understood the situation, while Ganondorf is typically outcasted from society and unaccepted. Groose's potential lineage might happen, but that's a lot of speculation. Loved the ending and how we understand that these characters are the beginning of the lineages for all the other games, nicely done.
