I think Gabe over at Penny Arcade has finally reached that point:
The real reason I got it was for the sticker book it comes with. Yes that’s right, a sticker book with 400 stickers! Every time you meet a character or get an item you take the corresponding sticker off and place it next to the picture in the journal. Try to imagine a 28 year old man squealing in a high pitched voice to his wife in the other room. “Ooh honey I just met Mulan, I get to put her sticker in the journal, I GET TO PUT HER STICKER IN THE JOURNAL!”Yeah because I would have never guessed that about him.
