Rolling the Marble

NASA has a game out: Where on the Blue Marble?
 I am not entirely certain that the game lives up to its lofty ideal : crowd sourcing geographical points of interest. I suspect a data set of Google Earth lookups would do a better job.
But anyways, whats considered a good score? I can routinely get 1000 pts/game just by clicking on the center of the map.

 I would like to know what such a game strategy is doing to the NASA metrics.
