What's your favorite aspect of the Kingdom Hearts series?

Yoko Shimomura’s Music.

Unquestionably her music is the best thing about KH & really the only truly great thing this series has given us.

Definitely the music, gameplay is a close second and then the story.

Going to have to go with story, though it's by no means perfect and has a lot of valid criticisms it's what always keeps me looking forward to future entries. 

All aspects are definitely important though, and the games wouldn't be the same without them all working together.  

Mostly the story and setting. Of course I do love the character and world design, the music score, and combat gameplay.

fighting disney villains, so gameplay

Definitely character design and music (it is what got me to KH in the first place) ^^

The story and Disney settings, but also the themes and ideas the series presents 

Mainly the idea of fighting monsters shaped after the worlds of Disney movies.

For me it's a tie between music and story. Neither would be as memorable or emotional for me without the other.

My favorite aspect of the Kingdom Hearts series is the boss fights.  Boss fights are my favorite parts of every videogame, and the boss fights of the Kingdom Hearts series are some of the best in my opinion.  However, since that isn't an option, I would say that the story is my favorite aspect.  I love storytelling, and despite how crazy the story has become, I love it anyway.  The music is pretty much tied with the story because Yoko Shimomura is just too good at being a composer, but the story just barely wins for me.

The personality of the characters... They're each different and interesting, and most of them are well written (especially the darling Riku). So the story, I suppose? That's the closest one.

I find it very interesting that gameplay is the least voted, while I love the plot and the music is second-to-none the gameplay is 100% my favorite part. 

This is cruel, why isn't their an "all of the above" option? 

I fell in love with all four aspects of the series (granted, for some games they're not always even)!

I can't choose just one! Everything, from the story to the characters to the setting and music and gameplay...it's all amazing! Truly an unforgettable thing to experience!

I love the gameplay and music for sure, but my favorite aspect of Kingdom Hearts is the characters. I love these characters to death.
