Same thing happened to me when I played a demo about a week ago. It was definitely less than 30 seconds.Matt K said:I actually tried one out a few days ago and I got pretty bad eye ache within a few seconds.
That being said, this isn't rocket science here. I just stopped playing.
I can also see where people might be coming from though. Nintendo has been hyping this thing up for a while now, so I can see how it might be upsetting to have spent $250 on what Nintendo was advertising, only to get a headache 10 minutes after taking it out of the box.
This really just boils down to being a more responsible and informed consumer.
