1up.com has a piece looking at the changing variable of game length, and current gamer tastes when it comes to time investment. From the article: "For better or worse, one of the main ways gamers size up a game's value is by length. After all, an RPG that promises 40 hours of gameplay must be superior to one that offers a mere 20, right? Not quite. The fallacies here are obvious enough. For example, what good is 40 hours of content if only 20 are worth paying attention to? Or what if a game takes ten hours to run through, but is eminently replayable? Despite these and other valid arguments, many gamers, especially in recent years, have subscribed to the 'longer is better' school of thought, without really considering what 'longer' actually means."
