Nope, can't say I have. But, now that you have brought it up, I will probably start to notice it. In the beginning it will be innocent and unobtrusive. Over time it will build up into this huge monster of an annoyance: I will no long see beautifully rendered GCN goodness but 3s, 5s, and 7s floating all over the screen. It will reach a critical point when, after I've stopped playing, the numbers persist in my vision, going forth to infect every part of my life.
