I voted for the fourth one for the reasons I expressed in the other thread. The title 'Broken Sword: The Sleeping Dragon' already conjures up ideas of adventuring, exploration, and story. Don't underestimate its properties to spark the viewer's imagination, you don't necessarily need a picture of characters to show this. Therefore, what's left is the graphic itself, which abstractly conveys mystery and progression and modernness (both in story and game's look and overall design), leaving it up to the viewer to imagine what's in store. The symbol suggests ancient qualities, magic and mysticism. One glance at this box and you know what you might be getting into, although you can't quite place it, but you know it's gonna be good.
