[P.J.]

Finally, my English degree is useful!

One aspect that I think many people are ignoring are the creatures represented on the flags, the griffin and the dragon. The griffin appears far too many times to just be random, and is even the first thing shown in the trailer. They could have just as easily chosen a different creature (unicorn, wolf, stag, Frank's face, whatever) or just left the flags solid colors. So I feel like the fact that they had designs on these flags has to have some sort of significance.

So the question becomes, what do both of these creatures have in common?

As someone a few posts above pointed out, they both have wings. But I'm not even going to go there.

In the myths of both griffins and dragons, one recurring theme is that the creatures are obsessed with their hoards of treasure. So what if each alliance has a set "hoard" of some sort (tennis balls?). They each begin the game with a certain amount of treasure, maybe spread through a few different goals/baskets/scoring areas and they have to both protect their "hoard" while trying to steal from the "hoard" of the other alliance. What would one use to protect their hoard? A stronghold, of course.

That's all I've got.
