Awesome is better than more.

I have to agree… Awesome is better than more.

No matter, says Casey Willis, an avid gamer from Atlanta. "Make a game worth my time and money, and I’ll be happy. After all, 10 hours of awesome is better than 20 hours of boring."

My observation is that more than a few studios build a game and then feel the need to pad it and add more at the end… I hope this means that more developers are actively designing for story length up front.

Better to add features that give significant replay value for the folks who want more, and drop DLC to extend the long tail in digestible chunks over time.
