I disagree completely. To The Moon for example. That game was only 6 hours long and I felt more invested and more emotionally stirred by the plot and characters than I did in many 40+ RPG epics. Sometimes a story that hits fast, hits hard, hits home, and is to the point is far more effective than one with verbose padding.
Good example is Benjamin Button. Beautiful short story. The movie was overly long, boring, and too drawn out. It ruined a perfectly good short story with all that padding, hoosefudge, and drag.
...and it's healthiest to eat 5-6 small meals a day anyway because we're grazers, but that's another discussion for another time and place:P Snacking rules! SHort stories rule too!
