Don't get me wrong, I've got no arguements against the greatness of VI. That game had obsessorific features that kept the geeky fanboy in me happy for years... like beating the game with *only* the three chracters it requires you to pick up after the world goes to shit. There were ways in which I thought that they got some things perfect in that game that they failed to recreate in future installments, like the fact that as much as I liked materia, I also liked it when characters had individual skills (and while IX gave them individual skills, they mucked up other things in the process... garg!).
The only thing I truly disliked about VII aside from the translation was that I wish more of the game took place in Midgar... the place was frickin' huge and you only got to visit maybe 10% of the whole city. Besides that, it was just a damn cool setting.
I haven't played X yet... don't have a PS2.
Oh and Bazilla, the ending of FF VII is supposed to be confusing from what I gather. I remember hating it at first, but I think what they wanted you to do was to reflect on things as opposed to having it all spelled out for you. It's certainly a better ending than IV had, that's for sure.
