My parents ordered the first issue of Nintendo Power for me in 1990 as a back issue so I could utilize the guide for the 2nd Quest in The Legend of Zelda. I couldn't finish it back then because it was too difficult for me. I finished the first quest and, for the first time, the 2nd quest this year. I remember still looking through the pages of the first issue for advice, notably the description of the red and blue bubbles.
