Did you mean to put this in the FFVIII forum?
FFVII is my favorite game of all time. It's just amazing. FFVI is good too, but I like FFVII better...maybe because it was my first? I'm not sure.
It's like TehAbominatrix initially said though: people don't hate FFVII so much as they get annoyed by all the rabid FFVII fanboys. I'm an FFVII fan, but even I get annoyed by that. FFVI is great, as well as FFX. I don't really think FFVI has a story that can compare, and though the characters are lovable, they don't have very much depth because there's just too many of them. Still a great game though.
FFVII is the most popular though because it was the first to be 3D, and it came out right when everyone in America started buying Playstations. American FFIII(FFVI) was pretty popular in the SNES days too though.
