[Late entry, but I want to take part in EVERY one of these!]
This game was an instant classic when it was released. At the time, I was a little 8 year old kid with a brand new Nintendo 64 with no knowledge of what video games were. Most of the time I had little to no idea what I was doing, but slowly as I picked up on it, it became my life.
Think about how impressionable an 8 year old child is. Now think about how awesome Ocarina of Time's story and gameplay is. Need I say more?
This game took about two years for me to beat, and it took many more years (and countless play-throughs) after that for me to fully understand and appreciate what this game is. Thinking back on it now, I am thankful and proud to say that I was part of the generation that grew up with Ocarina of Time.
