The idea is these would act like artificial planets. I imagine they should be very costly and price should depend on NW like a defense station.
They would appear in the system page just like a planet would, but with a space station graphic of course.
You will build infra on these just like a planet, maybe different prices for different sized stations. You should be able to move these space stations around to any system that you control. Perhaps the more stations you have in a system the less effective they are. Like a 25% reduction for each additional station per system.
They should be much easier to be blown up than a real planet when attacked. A few options here… make it so they cannot be taken over, only blown… or maybe make the NW threshold 75%+, or just make the outcome of taking control of the station vs blowing it like a 1 out of 5 chance of keeping it.
They should also count as a planet in your size ranking.
These would work similarly to Space Stations, except they can go into systems you do not own, and would act as a mobile portal. They should also be fairly expensive and price adjust to amount of NW/Planets.
You should be able to build lasers on these to protect them. And since they have a portal, your full fleet should be able to protect them. They should also travel at standard speed like a defense station…
I think they should have a limit of how far they can travel, maybe 8 to 10 tics max from your nearest portal. If they enter an enemy defense station they are immediately destroyed.
I also think they should either not be able to be taken over, or a really small chance of it, 1 out of 10 or higher.
I think you could even add a new op to cloak the Fleet Cruiser for a few ticks.
So yea … just some ideas rolling around in the old noggin.
