I see. I wondered! Had never heard of it but am not a gamer. I'm not coordinated for it since I'm discalculate and tend to reverse things. I'm better at games where I don't have to worry about direction, but even in solitaire I tend to try and put black on red and vice versa. I used to sit with my son as he would play Indiana Jones on the Atarii. Personally, I could never get off the first screen, but I could watch him play and offer suggestions!
