Starsector 0.96a is out! (05/05/23); Blog post: Colony Crises (11/24/23)
Perhaps a less abrupt solution would fit better:When you are in possession of all of the capture points, the radius of vision that those capture points steadily increases until maybe 30 seconds to a minute after you've taken them all, you can see the entire map.That removes the possibility of being able to hide in a corner without enforcing any abrupt battle end.(For simpler, first-pass implementation, just have it reveal all view as soon as you capture them all, though I don't like that quite as much, it's still quite abrupt. Would certainly give a nice benefit to having them all though.)
The game was completed 8 years ago and we get a free expansion every year.
Arranging holidays in an embrace with the Starsector is priceless.
...by the time you hold all objectives you're probably dominant anyway.
