I officially spent too much time on this thread.
Final Fantasy VII: It was graphically amazing at the time, but I really didn't care for any of the characters. The "tragic" moment didn't really phase me at all since I didn't care. I basically felt sorry for the villain, and killing him didn't feel as good as killing the villain in FFVI (wow I am making an effort to keep this spoiler-free). The music wasn't bad, but it couldn't hold a candle to VI's soundtrack. I liked the Materia system, but I prefered VIII's Junction system. It wasn't the worst FF, but I feel like people give it a lot more credit than it deserves (though it did greatly help RPGs become mainstream). At the time, I liked it, but playing it now is kinda boring.
Final Fantasy V: Worst soundtrack in the series. The job system is cool but I liked using it in Tactics way more, where it actually makes sense to have an archer instead of a knight sometimes (instead of to build up getting an ability like X-strike or whatever). Boring story. Completely dull characters. Villain with a stupid name made it hard for me to take seriously. Worse graphics than IV. Everyone who played the Japanese release (or translated ROM) hyped and rated this one to be the best in the series after we got VI, but I really don't see what's so great about it. Maybe I would have liked it if I didn't play FF Tactics first, but I did, and I prefer the job system there (not to mention its superior all around gameplay and presentation).
Castlevania Harmony of Dissonance: Graphically superior to CotM, but worse music than the other GBA iterations. Too easy in comparison to the more pleasureful difficulty of CotM. Not grand enough to hold a candle to AoS or SotN, but it sure tried its hardest to be like Symphony. No replay value (different modes in CotM were fun and challenging). A decent game, but it did not deserve the ratings it received. Boring magic system in comparison to CotM. Boring items in comparison to AoS. Lack of hidden areas.
