I'm ready to fight Ganon, I think, but I have a bunch of things I want to do first.
I've defeated all 4 beasts, experienced all memories, and have the Master Sword.
I want to complete all shrines (on 75ish), upgrade my Knights Armour, Guardian Armour, and my Hero's Tunic fully, find the Hylian Shield, and complete a few more of my sidequests.
I've no idea how long this will take me though.
