Man, this really takes me back. I played this game endlessly as a kid. It was the first game I remember having a save file option, which was revolutionary to me, because before that when I was in the middle of a game I just had to pause and turn the TV off and hope my parents or siblings didn’t hit the on/off button on the NES console. That music is still burned into my mind three decades later.
Somehow I never realized until about a year ago that it spawned a long-running series under the name Dragon Quest (now up to eleven games) that still continues to this day.
