How many hours should a single player game today be to warrant a sixty dollar purchase?

There is much more to a game than its length, so I don't put a great amount of emphasis on it when I'm deciding whether or not to buy a game. For example, Journey is an incredibly short game, but it is also an amazing experience that I feel is worth every penny.

Yes, but you can buy the Journey download for $15 dollars. Its well worth it.
