The first three aren't bad but I would only recommend them if you're really into old jrpgs.
4, 5 and 6 are pretty good.
7, 8 and 9 are the best in the series. I'd say start with 7.
Haven't played 10 and everything after looks like a steady decline until the series becomes actual shit. FF7 Remake looks like it's shit too.
