Hmmm. Well, I do agree with you to some extent. I'm not too sure if I'd consider Final Fantasy 7 one of the best RPGs ever.
It was very good, the story and everything. Hmmm... yeah, I guess I would, but the only thing that makes me hesitate is that so many people like it. All I ever hear about it, rather all I ever heard about it was "Wow! Those Graphics Are AMAZING!" "Sephiroth is AWESOME!" That seems to be the majority's opinion, many of which haven't even played any of the older ones. But, I digress.
One point of conflict between your ideas and mine is that I do not believe all of the other FF games "suck." Well, you excluded FF5. Final Fantasy 1 was a very good game. Although it lacks in story, it is there it's just not spoon fed to you like the new games, it is quite fun. FF2, I can't say I liked it. Although it was never brought over from Japan, it lacked the fun factor FF1 had. FF2 had character development and plot, surprising for a NES game, but it was just no fun to play. FF3 seemed like taking a step backwards in the Story and Character Development area, but it was very fun and made a base for the future FF5 and FF Tactics job systems. FF4, is one of my all time favorites. Very good character development, Very good plot, and it's loads of fun to play. FF6 is also very good. The whole Opera setting was very cool, I thought. There is plenty of character development, and there are a lot of characters to develop. The story was very good as well.
FF7, it was good, I've already mentioned my veiw beforehand.
Final Fantasy Tactics did not follow the traditional FF style. FFT is a strategy/RPG and one of my favorite games of all time. It's job system is amazing, and the plot blew me away.
FF8, it was alright for a game, but it didn't live up to my expectations of an FF game. Junctioning wasn't much fun. Innovative, I'll give it that. But you could max out your characters at low levels, personally I was maxed out at level 23. Those world Map Draw points made it simple. And Encounter-none made the last level quite simple as well. The story was alright, but I was getting sick of the main character who doesn't care about anything.
FF9, once you got past all of the references to the older FFs, and all the nostalgia, and there was plenty, it wasn't much. The plots been done, characters were nothing special.
FFX, not my cup of tea. Basically, my opinion is the same as FF8, only replace Junctioning with Sphere Grid, and Negative Main character with Sissy, whinny character.
But, these are only my opinions.
