Personalize Media has a video out with a summary of the virtual worlds out there. Far from all are included! Most of these are non-game social worlds and there’s loads that I haven’t even heard of! I was suprised to see A Tale in the Desert there, though. For one, I thought they definitely qualified as a game and second because I thought their numbers were so low that they wouldn’t survive. A Tale in the Desert is a great idea – and I’m so incredibly happy that they’re still alive! That really is good news.
