Mind controlled video games

In a recent story on CNN and in Scientific American, there were articles about a man who had an artificial arm that was able to be controlled by his own brainwaves. Pretty advanced and amazing technology to re-wire brain waves!

That said, it was rather interesting when I came across webpage of a company that has a product that creates a brain/computer interface. One of their claims is that they have a way by which people can play video games with their minds! It sounds amazing and interesting! It also calls up the question as to what makes a video game fun. Would a video game be equally as fun if you played it with your mind rather than the manual manipulations to a controller? Based on our readings, it should still be fun assuming there are goals, outcomes and challenges, although the challenge may seem to be diminished having taken away the hand-eye-coordination component...
