Extra Credits

In case you don't know, there is an online show that explores various topics in gaming called Extra Credits. If you're interested in things like design philosophy, gaming as an emerging art form, or media portrayal, I highly recommend it. If, however, you're the kind of person who says 'politically correct' a lot then you probably won't like many of these episodes.

Here are a few good episodes to start with:

That show is great. I used to watch it when it was still on the Escapist.
E especially like how they are able to view things from a broader perspective and come to conclusions that can be transferred to different aspects in life.
