The sessions themselves are pretty expensive, but I believe that they do count for credit that you can put toward a degree. I believe non-students can also take it for non-credit status, which might be cheaper? Unfortunately, I don't set the price, so all I can do is to try to help you get your moneys' worth. You can look at the Github for "Building Worlds", the (15 week) Unity course I'm teaching at Parsons right now -- as well as a blog post on my general approach to game development education.
You'll, uh, also get to hang out with me, I guess. That's a perk, right?
