I’ve traveled through several online worlds and have experience with many virtual worlds, MMOG’s, etc. Each online space has their plusses and minuses. In my years of “traveling” I’ve never seen anything as robust, creative and open-ended as Second Life. While I’m always surprised by the complaints that are made about Second Life, some legitimate others are mindless, I never understood it. Many people make it sound easy to build a virtual world, but everyone is learning that’s not the case. While many people complain about Linden Lab’s management of a virtual world; there isn’t much competition in their space mainly because of the difficulty of creating and maintaining a robust, integrated virtual world with mass appeal. Sony has been learning that lesson along with their recent delay of PlayStation Home, a virtual world more akin to There.com than Second Life.
