I never thought of it in terms of movie ticket prices. I used to say that I wanted an hour per dollar, but it's not always that way. I don't mind paying more for a solid game that's a little shorter. I don't pay $60 for a 10 hour game typically though, no matter how good it's supposed to be.
I think that may have been more true in antiquity than it is now, if we use narrative-based games as a common theme. Portal is a pretty recent example of this rule not being true anymore. So's Mirror's Edge (I know, not as universally loved, but I thought it was great) and other games like that.
Still, I think games could do with more consistent pricing brackets, even for big-name titles. I always felt highly insulted paying full price for Dragon Warrior VII, when its final product couldn't hold a bloody candle to games from two generations ago. For the "oldschool" effect, Suikoden II was worlds better, and for narrative, a game like Xenogears was far more concise and meaningful. Not to say it was a cheap game to produce, but it certainly couldn't have been that expensive compared to its contemporaries.
