Is there any plans of implementing stationary system defences, that are capable of fighting off fleets trying to invade the system?

You mean like a fleet you don't move? I would think that adv cultures would realize that static defenses are pointless...unlike us.

I mean stationary defences, like this one: http://stargate.wikia.com/wiki/Lagrangian_Point_satellite



The fleets approaching travelling at FTL speeds (sub-space, warp drive etc) will eventually drop out of it and into normal space, into normal space, at which point point defence weapons could take them out.

Assuming the civilisations are capable of travelling at FTL speeds, they should also be capable of tracking ships travelling using it.

static defenses have always had a major advantage throughout history against armies and navy's. they can usually afford to be larger and have more guns as they do not need to move. however in the world of sci fi they lose quite a few of these advantages. more guns has always been better in the past but with nuclear warheads and other missiles, defenses in place would be easy to destroy. it is also likely that the defensive structure would require movement to avoid hazards such as asteroids, solar flares, etc. also you wouldn't want an enemy fleet knowing exactly where you would be before they even enter the system. as for gameplay purposes, static defenses would likely be installations that can take a ton of damage and give out lots of damage also. realistically there would be no need of of command points and fleets for these interstellar garrisons. to balance this they would likely be hugely expensive to produce and probably to maintain too. although the most effective would be manned stations with guns, there are also other possibilities such as ai defenses or perhaps giant, globular space mines. just my thoughts on this matter.

I like space mines.

I remember in one episode of SG-1, they were encountering a minefield (space mines). The mines were "smart", able to home in on the enemies, and they could also be reprogrammed to attack any enemy of their choosing. They also had internal stabilisers and thrusters, able to move around asteroids and such.



Any "stationary" defences could also be equipped with shields, that - if upgraded - could withstand a lot of firepower.

They could also have manoeuvring thrusters, so that they could be moved around.



Considering how the weapons in Endless Space are relatively primitive (kinetic and missiles are quite easy to either block or intercept), shielding should be rather efficient.





I'm actually surprised at how a strategy game which involves conquering other lands and defending your own land does not, in any way, have static defences.

It's best not to think too seriously about science fiction. That said, I find the ideal appealing on the surface, but what does it really address in the gameplay and mechanics? If you can't build GCD's to effectively defend your systems, how is adding a slightly cheaper defense for space combat going to change anything? If space defenses are too powerful, nobody attacks, too weak and nobody uses them.



It's just another spoke of things to balance in the wheel of combat. Not that I wouldn't welcome that addition, but with things as they are now, I'd rather see them go after some low hanging fruit in terms of mechanics and interface.

it would be interesting if you could do more with the existing defense facility that you build in asteroid belts if you could turn it into a ship type and improvement and add modules to it to change its behavior. practically, asteroids would make excellent defensive areas, much better than open space, and the amount of moving objects would provide cover and might make it harder to target even static defenses. also a facility in place for a length of time would be able to track and predict the movements of asteroids and perhaps use it to their advantage. also as for balancing, as asteroids cannot be terraformed, it would mean you can only have a few of these, perhaps one per asteroid belt? and it would make asteroids a lot more valuable than they are right now.

Space mines sound like an interesting and fun idea. I'd like the capability to carry them on flagships, perhaps as a heavy load. I remember using space mines in an old Tradewars battle as a desperation weapon. I didn't have a ship powerful enough to defeat my enemy, so I dropped mines around his ship. When he logged on, he immediately blew up. Sure, I died too, but it was fun.



Maybe something that could be used as a flexible defense/desperation offense package like that. A suicide weapon of sorts.
