When I first saw this photo, I was was struck by how much the results reflected the approach I've been taking when photographing subjects in bright sunlight. If you look at the gamer walking to the right, you can see how little detail the shadows would have if a flash was not present. It appears to have been feathered (turned away) to prevent the leftmost (nearest) subject from being burnt to a crisp. All in all, a very nice piece of work!
If there a moral to this story, it's that sometimes a flash is the only way you can produce a usable image. Having a flash to add detail to the shadows means you don't have to compromise your exposure. The sky is exposed to give an appealing blue, while the flash gives light back to the underexposed shadows.
So keep a good flash with you at all times. I has saved the day for me more than once!
