You know, it's perfectly OK to use the phrase "Pandora's Box".
Legends are supposed to change over time, and the product's logo is obviously a reference to the modern version, not the ancient one.
If we were making a Robin Hood game we wouldn't need Wikipedia fueled "experts" telling us that Maid Marrian and Friar Tuck aren't really part of the Robin Hood story.
On the topic of the game itself, perhaps the number 3000 could take on mystical significance. (Perhaps 3,000 coins to collect to get 100% completion?)
Either that or whatever the real pre-order number turns out to be.
