If you can build ports, you should be able to blow them up. It'd be a cool way to attack traders. An attacker could scout out a trader's major trade route and blow it up. They could come into an SG, blow up any colo ports, and slow down colonization.

That would actually be very cool. How about orbital battle stations too?

But you can't create own port, it is only with SG torps But idea about destroying ports... Strong player after some time should destroy every port in universe

This is one of the changes in 1.00. When you create an SG sector it will not have ant planets or ports. You will have to build them using commodities like ore, energy, etc. The ports that can be built can also be destroyed but they can defend themselves.

Alright!
