It was really cool to be able to play the role of the richest duck in the world as he traveled around the world (and to the moon!) searching for treasures

The plot is that Scrooge McDuck, the richest duck in the world, wants to be even richer by traveling around the world, finding treasures

You play as Scrooge McDuck and you are trying to become the richest Duck in the world (if he wasn't already).
