I've been playing for quiet a while and was really wishing for more defenses. So I started thinking and wondered if it would be possible insert a planetary defense upgrade to the planet menu. You upgrade everything now, except for defenses, but it would be great it you could build defense satellites that would attack ships that get too close, like pillagers and siege frigates. It would give you another way to defend your planet from pirate attacks as well as make it a little harder to destroy an opponents planets.
It is only logical that people would never leave their planet in the hands of just a few turrets out in space, something closer would be get. Maybe you could have different stages of planet defense. One could be gauss cannons, the other gauss and missiles, the other something else, like more fighter and bomber generation. It would just give the game another get dynamic. As of now, the planets are really vulnerable.
What do you all think about it?
