Got the toys?
I haven't seen it yet either, but I've got a number of the toys. They are nifty little things (though I think some are a bit too flimsy for the age group).
If you've never seen the toys:
They come in sets of cards and spheres. There are cards (heavy cards) that give bonuses and penalties to each of the factions. You shoot spheres, you modify numbers, you see who won. It kind of reminds me of marbles, except with magnets that cause the marbles to turn into monsters. A satisfying visual battle.
I'd heard that with the anime release the toys will be going to the US. I certianly hope they tweak the construction a bit on some of the weaker models!
