Playing ‘war’ with tops was a new idea to me until my 6 year old grandson introduced me to Beyblades. It seems to have come back in fashion with a bang, from Japan, and tied into a TV programme. We didn’t fight with tops when I was young, or at least, ‘my lot’ didn’t. Here’s a site about Beyblades, there are many others.
