Do you remember the first chapter of Harry Potter's story? In the end of the book Joanne Rowling discribes an incredible chess battle which took place with the huge firgures who would fight against each other for real and destroy each other with their thrones, swords and other things they have "in stock". Sounds absolutely amazing, doesn't it? Sadly it was the only game which was shown like that in a movie, but it looks like another terrific game of such kind has just been played - this time it's battleship, and yes, the ships are real!
