Just as addictive as everyone said. It reminds me of racquetball, which I could play for hours. But racquetball required going to the gym, getting dressed, finding someone to play with, waiting for an empty court, coming home. It might be possible to use my DDR scores as a measure of something.
I recently got an ipod touch free with another purchase and when I started using it I thought of your posts about using your laptop to measure the effects of omega-3s. It seems like the ipod/iphone/touch screen smartphone would be an ideal format for games that test for the effects of things like omega-3s. The games could be made fun enough to be interesting and the device is portable enough to take with you anywhere.
David, yeah, I agree, you could do the test while you’re waiting for something.
Something similar to the game Brain Age I have for my Nintendo DS perhaps?
