Which FFs would you classify as "dark?"

[Six]

I'll go with VIII.

Though seven was quite mysterious also, I felt that VIII was alot harder to understand, a lot more detail as to lets say... The unknown side. Keeps you wondering. The things happening in the plot, and the things you find out later on... Yeah... Definitely think VIII is the dark FF.

obviously FF VI, VII, and VIII but i also think in a twisted way that XII and XIII are dark. they have a dark tone with good/light winning in the end as all the ffs do. but the other side is these games are also very much on the light side. they have a very deep sense and story of hope and light that i think is why those particular ffs sell so well
