I feel like I'm not enjoying the narrative of The Legend of Zelda: Twilight Princess as much as I could, since I've had everything spoiled for me, beforehand.
I went into this game knowing what happens to Midna at the end, about Gannondorf, the Mirror of Twilight, Zelda's sacrifice, Wolf Link, that one NPC's head turning around to make a creepy face, that creepy cutscene you get after bringing back the last batch of light tears, Ooccoo's entire race, the invisible rats, and Zant's insanity. So many surprises and plot twists were waiting for me in this game, and I already knew about each and every one of them before I'd even started. Also, I'm still waiting for the bit where I can see Midna without that crown/mask thing on her head.
