I haven't played it myself, but my friend has told me that it was a piece of shit of a game. Also, most people on the internet have also expressed the massive flaws of it.

FF8 is wonderful. The story, the graphics (for its time), the summons (called Guardian force or GF for short in ff8) are amazing. The whole game is way better than ff7.

I usually replay it once every year or two cause I love it so much and it's my favorite FF. FF9 is also fantastic and highly recommended.

It divides opinions, but most people agree that it's a good game. It's about how good exactly it is that they don't agree about. And of course there's some people that can't stand some aspects of the game. But most likely it will be an enjoyable experience.

Not my favorite because of the combat system. Story wise is up there with IX and VII and it's probably the biggest of the 3 in terms of the story and with many plot twists (at least it felt longer to me even though I played through it just once).

Primarily on the internet though.  FFXIII is a different story and the internet hate probably more inline with the mainstream (how often do you hear people say they loved FFXIII, not liked, loved), but I heard lots of great things from people who played FF8 when it came out.  I'm more inclined to believe the mainstream have a lot of love for FF8.

FFVIII is the best of the PS1 trilogy, but its FF expect a million different answers.

Are there any FFs that are borderline unplayable? I kinda wanna play the whole series. 

That card game was amazing, especially the music.  

is very easy to level up on Final Fantasy VIII, you just need to get 1000 EXP for level up on every level.

Nah, all are pretty good. Just  don't download FF5 on PSN, it's a bit broken. It's fine on other devices though
