Well... this is the hardest poll I've ever tried to vote to. That's because I truly madly deeply hate both VII and VIII.

Well, I can try to confirm which one I don't hate as much, but...

FFVIII Hate List

I hate Squall. And Renzokuken.
I hate Rinoa. And Angelo (the Limit Break - how can I hate a dog? @_@)
I actually LOVE Angel Wing.
I TRULY MADLY DEEPLY hate Squall/Rinoa. And Squall/Seifer. And all the other pairings.
I hate Zell's Duel and Sephie's Slots.
I don't hate any of the other playable characters, but since they are not developed AT ALL, I can't like them.
I actually LIKE Edea. She would be perfect as the true villain.
I TRULY MADLY DEEPLY hate Seifer. No hate for Fujin and Raijin though.
I hate Ultimecia and her total lack of development.
I totally hate Junction system and how monsters "level up with you". The game is waaay too easy either if you overlevel or if you don't level up at all.
I actually LOVE Triple Triad. But the Chocobo mini-game is booooring.
I hate Quezacotl/Quetzalcoatl. I want my Ramuh. I also hate Pandemona. But I loved Doomtrain. <3

Veredict? I REALLY hate FFVII waaay more than FFVIII. =X *votes on FFVIII* I still don't like FFVIII, though.
