My story with Spirit Tracks is... interesting.
I vaguely remember wanting to buy Spirit Tracks some time in 2010, but I didn't. While it was the first Zelda game I played, it wasn't the first one I owned. I had previously downloaded Four Swords and The Minish Cap onto my 3DS (which broke in October 2012; luckily, I got a new one), but was too nervous to play either of them. I almost brought Spirit Tracks one day in November 2011, but for some weird reason I was too nervous to buy that too. I decided to find out what the game was like... by looking up a YouTube video of Sky Tower, then clicking through related videos until I found some Spirit Tracks videos. Incidentally, even though I'm from England, I'm more used to the American names because of these videos. Also, between while looking for Spirit Tracks music, I discovered the A Link to the Past Soundtrack.
Anyway, through reading the comments on those videos, I learned more about the game... and eventually found out all the spoilers, with the help of ZeldaWiki. When I finally brought it on February 11th 2012, I didn't play it until the next day, then put the game down 12 days later and couldn't pick it back up again until August 2014. In the meantime, I watched the ending cutscene on YouTube multiple times. Oops.
Still, my nervousness about playing the game caused me to come up with lots of crazy ideas about what it would be like. While most of those ideas were completely wrong, they still gave me a sense of "wonder" about this game.
In the interval between Nov '11 and Feb '12, I also kept watching the trailer
on the Wii's Nintendo Channel (*MLG sad music plays*). The music completely blew my mind; I never thought I could like any video game music more than Sky Tower. I was wrong. I like the trailer version more than the in-game version.
