Fans are using StarCraft II's editing tools
to build a World of Starcraft MMO. Yes, you read that right. Ryan
Winzen of Winzen Productions (which isn't affiliated with Blizzard) is
currently working on the game, and you can watch it in action in the
pre-alpha video after the jump. It's definitely worth a look.

Below the video you'll find a letter that Winzen wrote to Blizzard and published on the World of Starcraft forums today. It sheds some light on why he's working on the project. Check out the forums for more details on the game.
