- Kingdom Hearts

Not a book, but it struck me as sort of encompassing my feelings of KH as a whole. There aren't many games that are about family/friendship. Both are really important to me, so it gets kind of stale seeing the same romance subplot in all the shit I play, or watch, or sometimes even read. Beyond that, I think it's hard to talk about friendship without sounding cheesy or even infantile, and KH bypasses that pitfall rather gracefully.

It's the same reason why my sister and I love Gravity Falls. When the show's creator was pitching it to different networks, he always got the same response - "So the siblings are supposed to hate each other, right?" Part of his response:

They've known each other forever. They should occasionally finish each other sentences, they should recognize when one of them is about to do something they always do, they should reference past inside jokes, they should get instantly angry at each other and then instantly make up, the way people who've known each other forever do.

Which is what my sister and I are like. If you can pull off familial concepts well in a TV show or book or movie or game or whatever, I'll find it pretty impressive.
