USC course: Designing Online Multiplayer Environments

Here's the course site for USC's CTIN 482: Designing Online Multiplayer Environments. They are using Second Life for their work. The course site itself is based around a blog, much like ours. At first glance I didn't see the depth of resources here that I thought I might, but it's probably worth further poking around. Looks like they are also using Salen and Zimmerman's Rules of Play.
