I have a few places that annoy me in FF games. 1. The dark elf cave in FFIV where you can't use metal equipment otherwise your party members will be useless in battle. 2. The pyramid areas in FFV. 3. the Great Glacier in FFVII that place is the devil. 4. The mini cave in FFIII. 5. That one area in FFXII where you can't use the mini radar to see where you're going. 6. The only other annoying location I can think of in a FF game is the Jade Passage in FFII. Those enemies in there are tough.
