thing is eight was an action adventure story with a happy ending ( i could relate to squall better than cloud).

10 and 10/2 were both romance, and although the hero didnt get to live his life with his girl they both loved each other and would oneday be united. they were both about coming to terms with life and moving on.

but seven...the world got knndlk'ed (insert rude word). cloud didnt really get togeather with aeris before she died, sephroth was a goody turned baddy turned nutter, almost EVERY character got trout on one way or another...and then the world went spoo at the end....FF7 was a tradgedy, thus overall darker i feel
