This is how I'm thinking it will play out for the opening cutscene
A knight rushes in,
"Link..."
"Yes sir?"
"Zelda was captured by Ganon, you must save her."
"Yes Sir!"
Then you play until you save Zelda.
I hope that's what'll happen at least
Ganon says,
“Link.. we meet again for the last time!”
Link replies,
“Let Zelda go! Let her go!”
Ganon laughs,
“The Princess is fine in my crystal! No harm will come to her!”
Link brandishes his sword,
“I will do what I must!”
Ganon chuckles,
“You will try!”
Link defeats Ganon
"Agh... no you have defeated me"
"Ha ha I win again," smirks, "Now to help the princess..."
"I'm sorry Zelda"
Crystal gets shot with bow
"Good bye."
"Noooooo!" Zelda cried.
