The Social Gaming Summit, held in San Francisco last Friday, has been explored here on the site by our own Akela Talamasca. Today the Worlds in Motion blog has a great writeup of a panel on user-generated content, with an emphasis on how that concept applies to online gaming. Industry luminaries including Three Rings' Daniel James touched base with attendees on what makes user content so compelling, why users create, and what game makers can do to incorporate player creations.Most interesting was their observation that virtual spaces were more important than virtual worlds per se. Jeremy Monroe, Director of Business Development for the makers of Habbo Hotel, offered this: "You have to make sure that you're bringing content that is suitable to all players in the world. So when we bring a piece of content that skews to one demographic we have to make sure that we bring more content that skews to the other demographics. Some games try to create different servers, such as a PvP vs. PvP situation. You have to give everybody equal opportunity and an equal number of tools to express themselves."
