ISLMA Conference next Friday on how to modify an existing open source software information literacy game designed by Scott Rice & Amy Harris to tailor it to your information literacy curriculum needs. What's so cool about this is that it's free and you can modify it using basic Windows software (Paint, Notepad) and create a feedback survey using free online software (GoogleDocs).
We've set up a site on our LibGuides to provide all of the resources you'll need to create your own game. We'll be putting up the slideshow, too, once we've finished it :)
