Hokage's Room

Hmmm I would have to say a really good 3-D battle ground would be inside of naruto, where the kyuubi is locked up at and every 1 1/2 min the ground shakes and you can hear the kyuubi growl and thrash around. Also when the ground shakes you should also be able to see the water on the ground splash around on the characters. You should also be able to walk on the kyuubis cage where the bars are at and if you are on it to long the kyuubi will snatch you in his cage and take some health away or one of his tails will come out the cage and you will be hit by it. You should also be able to see the kyuubi like in the anime. Big eyes ang huge gnarling teeth and when the kyuubi breathes you should see the mist from his breath seeping out the cage.
