According to The Shifted Librarian, "Karen Markey is a faculty member in the School of Information at the University of Michigan. Earlier this year, she received a small grant from the Delmas Foundation to build a prototype online board game that teaches students information-literacy skills. Her game prototype is now fully operational and is being tested and evaluated by a class of 75 undergraduates at the University of Michigan. They’ve just finished conducting interviews with student game players, but they haven’t had sufficient time to mull over interview data and analyze game play logs. They already recognize that the incentive for playing the game is a critical issue and future games must be intimately connected to a class assignment or project."
Although the game is not online for everyone, what information out there on it looks good. Good library instruction games/tutorials are few and far between.
Here are a few information links:
And here is a video of the game:
