I did a dramatic play-through of Kingdom Hearts 1 + 2 for my little sister. I had already beaten the game, knew which fights needed to be beaten with easy and which bosses to almost die at.
When she was 10 and I had just gotten Kingdom Hearts 1; the first encounter with Darkside on Destiny Islands made her cry and she actually had nightmares, but because it had Disney characters she wanted to see the game.
Same thing happened with Ocarina of Time, Majora's Mask (Oh the Moon), and Final Fantasy X.
after I did the dramatic play-through of Kingdom Hearts 1 she saw me playing Ocarina of Time and she wanted to know the story.
They are fun for me to play, but she just doesn't have the same gaming desire as I do, but she really does like the stories. They're like 40 hour movies. In between times when she wasn't watching the game I would do some level grinding if the next part is to appear easy. being very careful to not progress the story. If I didn't remember, I would just play through it and not save it.
It was actually quite fun.
