Nightmare Fuel / Dragon Quest I
The deserted town of Hauksness uses the eerie dungeon theme and is filled with wrecked shops, grown-over pavement and poisonous marshes. The really bad news is that "deserted" doesn't mean the town is empty, no; it's filled the strongest enemies in the overworld. It's partially adverted in the GBC remake though (where it's called Domdora) and turned into a Tear Jerker of sorts instead, as the music playing in that version is actually the Requiem from Dragon Quest II.
