I was in school today and i learned that the Piano was invented in 1764, or something close to that. Now at the end of Ocarina of Time, Ganondorf was playing a piano. So does that mean Ocarina of Time, Adult timeline, takes place in 1771?if thats the case, then Twilight Princess would takle place in 1964 and Wind Waker, Phantom Hourglass, and Spirit Tracks will take place in the 1800. I highly doubt that nintendo woulda planned it like this, but you never know.
