User blog:Ej2333/Are super canons weapons of mass destruction?

Ive started to see some users using some "super canons" For example, khoi's jupiter and Docs (insert name here). They are also very powerful, some able to destroy an area of 2 cities. They do lack the Nuclear fall out though. Im feeling that in the future, some users might have the idea to make canons of their own and make it OP and able to fire across continents and destroy countries. So lets not ban these weapons all together. We should just impose limits.

-Firepower to size ratio

If your canon is just a 100m long hull block, it should not be able to do much damage, you have to put work into it for it to have any military value.

-Maximum destruction

At maximum, it should only be able to destroy large towns or small cities. It shouldnt be able to destroy a whole city.

-Range Limit

Well made artillery pieces should, at maximum only be able to fire a maximum range of a couple of countries away, so only in your continent,

example California to Argentina or Philippines to Tokyo would be allowed as long as its a huge and well made canon. However, Japan-West coast is ridiculous.
