Dragon Warrior IV > Nintendo NES

The King has sent you on a special mission to find out the cause of the missing village children. Go out into the world exploring, uncovering the truth and above all, find the children!

That was an amazingly cool Nintendo NES adventure game. If you'd like more excellent games from this genre then why not see how you go with more classics, like Chrono Trigger, Phantasy Star - The End of the Millennium and the ultimate Warrior of Rome.
