Horrible Histories World: Horrible Histories World is a virtual world which is inspired by the "Horrible Histories" book series by Terry Deary.  The premise involves the player travelling back in time and experiencing history.  The game includes 5 different virtual worlds: Putrid Pirates, Rotten Romans, Terrible Tudors, Measly Middles Ages, and Awful Egyptians.  It was put together by Scholastic Children's Books and Yomego Social Media Agency, and officially launched in August 2011.  The world was built on the Huzutech platform.  The publisher reported in November 2011 that: "We now have over 36,000 registered users to the Horrible Histories virtual world.  We are continually adding new content and hopefully this will improve.  The latest additions include a new game called Rat Runs, a joke machine and daily facts."  Other planned features included an online virtual good shop, a moderated chat feature, and events where subscribers would meet Terry Deary or a historical character.  The publishing and commercial director of Scholastic Children’s Books - Lisa Edwards - said: "We are very proud of the online Horrible Histories experience we have created and are delighted to make it available to every fan, in every corner of the globe.  In this way, it more closely reflects the Pottermore model".

Bragg v. Linden Lab: Bragg v. Linden Research, Inc., 487 F. Supp.  2d 593 (E.D.Pa.  2007), was a civil action (No. 06-4925) removed to the United States District Court for the Eastern District of Pennsylvania in October 2006.  Linden Lab, an online virtual world service provider of "Second Life" terminated the account of a user Marc Bragg when it discovered that he had found a way to acquire virtual land at a lower-than-market price.  The user brought this suit, which was ultimately settled before a final decision was reached.  However, the District Court did decide on two issues which may be important in future virtual world litigation: that the Second Life Terms of Service’s mandatory arbitration provision was unenforceable; and that interaction with a person in a virtual world can satisfy a state’s "minimum contacts" requirement for personal jurisdiction.
