Isn't the Twilight Palace considered a dungeon? I would've completely chosen that. Oh well. I reckon the City in the City is creepiest because of just how random it came upon in the came (I didn't see this one coming and I hate high places) and the history just being blank in the game about it almost. Just my opinion anyways
When i saw this on the forums page i was thinking "Palace of Twilight" for sure! It was a dungeon, u should add it on the list. It creeped me out everytime Zant's hands would come get u................... I had night mares the night after the first time i played that sectiion.
