Thanks for the helpful feedback on the Firefly and Serenity, guys!
@PelhamdsThat is one creepy looking Asteroid-city-ship-thing! You probably still have to get around to it, but there's some artifacts here and there around the edges of the hulk.
I'm working on a personal ride for the vanilla campaign. Going to turn it into a small mod as well, where you can start off in it. The ship is basically an enhanced Hound. I call her the "Fox". The idea is to keep on playing the Fox during the campaign; improving the ship and my personal skills. The Fox has more weapon slots than you can put guns on at the start of the campaign. But as your personal skills increase and you get more OP, you can start mounting more weapons on the ship. This is an idea I had for the Firefly-Serenity mod, but I'm now trying to execute it in vanilla Starsector.
If this seems like a fun idea to other people, I may create more of these mini-mods with personalised ships.
[edit]
Foxhound: 3x small ballistic, 1x medium ballistic, 1x small missile. Small bay for PD drones.
