Since we're talking about FFX, this should go in that forum. =)

I cried too. I don't think that makes anyone a dork, just because it's a video game. (I'm assuming that's why your sister called you a dork). If it was a movie, or a book, I doubt she would have said the same thing to you. It was an emotional ending, and I think if you really loved the game and/or the characters, it got some sort of response from you.
