Super ships isn't the most accurate of titles, but it works. I am a veteran of all of the escape velocity games. After reaching the end of the game, I always wanted something to demonstrate that success, and then new challenges to pit myself against. This is that desire made manifest.
The Voinian Ships, not balanced that well, but I am more than happy to share. Installation: Put the zipped file into gamelocation/Endless Sky/plugin folder. Note, the folder is not necessarily there, and you may need to create it.
