Voice acting.
Edit:
Realistically though: no handholding. I don't need everything pointed out to me in an adventure game. Part of the fun is dicovering things for yourself - see what works and what doesn't. Trial and error and all that. I also don't need the long tutorials that Skyward Sword has. Tell me "it's dangerous to go alone", give me a weapon and let the game begin. It's not that hard.
