Yeah exdeaths castle was just cool when I didnt realize what the design was. But when I did it got awesome.

not too sure of creepy locations since none really creep me out, some like the aforementioned underwater from ff7 are more sad to me. Although I do think the crashed gelnika is creepy, and the northern crater in disc 2 with the wind and lightning. Also I found the Fanatics tower in ff6 kinda creepy too, but now its more a feeling of revenge agajnst the magimaster for what he did on my first playthrough.
