I've finally got shipbuilding down to the point where I can do it competently. It's still twitchy and annoying, but ultimately worth the effort. I haven't built a ship from scratch yet, but I have altered the shit out of a couple of them. The last one is a Class C that I bought in Akila that had an interior layout like a maze initially. I streamlined it so all the important stuff is easily reachable, but it's still a work in progress. And of course all my ships are decked out in Chiefs colors.
The last thing I still haven't really done yet is outpost building; I did build some dogshit little iron producing post, but haven't visited it since. Tough assignment for the crewmember I stuck there, mainly just to get him off my ship. I'm still working on leveling up to the top of weapons and spacesuit modding, but that will be next. I plan to address it quickly in my next playthrough.
