7 Was the best. I'd pay 100 dollars for remake and 200 for special edition remake for the ps4. 8 Wasn't bad, ya the story was a little out there but once you push through things you can start to enjoy it some. But 9 was best after 7, in fact I started playing it a little again when I'm too tired to get up from recliner. But after that, I didn't care for any of the games besides 11(PC online)
I beat 10 but hated it.
Never finished 12, got too bored.
Almost finished 13 but again, got bored of it and story.
I'm eagerly awaiting Final Fantasy XV as it reminds me bit of FF7. Real hopeful it turns out good!
But if you have the wii, The Last Story was pretty good(Yes, it's more control base then motion controlled) but was a good story and game play. Bit more fast pace and easier to sit there and grind your levels out but that was last game that had a FF 7-9 feel to it.
