Before I read this post I thought I played a bit too much, I still haven't 6 figure. It seemed like every time I went to the Head or had to kill a few minutes I would play. I do play it, as long as it doesn't get much faster though since this type are about the only games I can play beside Solitaire on my Mac. Other game Systems may cause these symptoms depending on the game & the speed of the graphics, my wife plays & I even have issues spot watching her: Dizzy, light headedness, sweats, nausea. Now my daughter is turning 2 so she makes sure I she has my undivided attention.
