Remember trying to build something worth while with the Lego bricks and pieces only for it to all come crashing down then you sit on it? Well at least there was some good to come out of the destruction of your 'well' constructed structures (try saying that 5 times fast!) it was fun smashing and crushing it! The same fun can be had with Bridge Builder although you spend hours designing a perfectly executed structure only to have the train drop it like a soggy piece of bread. At least you can look back and laugh? before crying.
