Since its launch in November 2004, World of Warcraft (Wow) has become the most widely played massively multiplayer online (MMO) game in the world. When a popular WoW player died in real life, the people in the game think it would be nice to have a memorial for the player so they log into his account, take the character to a lake, and set it up for everyone to come pay their respects.
Another tribe decides this would be a great time to ambush everyone so they run over a hill, kill the dead guy's character, and then wipe out everyone who was there to show their respects. They filmed the whole thing and put it on the net.
