Yeah, I liked Epona. I particularly liked getting her. Link, horse whisperer. I never really loved her, because she did a few too many silly things involving awkward collision stuff and all that.
It's funny, though. Maybe it's just the sheer volume of play-throughs I've given OoT. But whatever it is, I always forget just how attached I became to so many of the characters. All of the sages, except Impa, who scared me. All the other people too. The whole last scene, the party, etc. I love it. Everyone in the game all gathered around, having a blast. Then, King Zora and Mido, two people who were were obstacles out of fondness for someone, both missing that someone. Then, the sages fly over. When they all appear, I smile every time. I'm smiling now.
This is why that will always be my favorite Zelda game. However much any other game may be awesome, may be more challenging, more interesting, just better, no other will get me as emotionally attached as OoT did.
