(I didn't know that there is no playtest before the results are decided)
Are you saying the judges didn't test the scenes, but only looked at them?
I tested all the scenes quite extensively, and did not miss all the great details - the shark in the water and the hidden grotto e.g. - in the Booty Beach scene.
Making bamboo huts with bamboo spears, gold coins with yellow dye, a necklace with maize... Not to mention the palmtree lookout post.
All those details and more, along with a good layout, a consistent style and flawless AI mesh, made me place that scene as the winner.
