I e always been a 5 fan. People say it’s just for the job class system, but they miss everything else. The characters are just so fun, and it’s in contrast to a plot where they are just always loosing, but growing with each other because of it. Honestly, I replayed 4 recently, and the love of it just seems like nostalgia compared to 5.
I think they're both still very good games. I just wanted to defend V's place in the era of FFs IV started since it gets dismissed as "not as story heavy" for some reason.
