Whats good in this, is that it prevents the player from insta poping a colony as soon as he enter the sector, the bad thing, however, is that it is encouraging turtling and a slow paced game.
maybe we should add a factor that will bring more stress on the player to expand earlier.
i can make the spawner graphic, what did you had in mind for its shape?
few other minor things - the colored ship in the interface circle should be clickable like the ship itself in order to show the elaborated stats window.
maybe more paths from and to each sectors, for better manouvering in the galaxy itself, both for the aliens and the player. just had a game today and the most fun was when a sector had 2 paths leading to it.
the sector defence ship is still a viable idea.. especially if you accept that more paths for each sector is needed, but we can alter this idea into something else, maybe have slot in the formation editor that allows to leave the ships in the sector for defence. it will seek the enemies and circle them while firing. this way the escort ship will remain viable if we make it a much faster ship to better respond to enemies in the sector, because right now, after the cruiser the escort isnt needed.
