Haha, I remember this one and loved it. Looking back, the game was quite a grind, and some of the key items were really hidden in random spots. Basically needed a game guide or help of a friend to find a lot of them. Old school Nintendo games were hard.
Dragon Warrior 2 was a little better but 3 and 4 still hold up today very well. They were all released on the us Nes but so rare I never even saw any if them or played them until decades later on emulators. I'm guessing 3 and 4 go for a tin of cash on eBay.
