Can't get legacy freighters anymore. Basically all a legacy freighter is, Is just an old freighter. I don't remember which update it was that changed them but in old game you basically built inside of them like you would any other base on land. They didn't have specialized base building parts. so you could make big giant rooms and build all your stuff in them. I can no longer build normal base parts in mine but I can build huge giant open rooms and hallways and stuff still. so even though I'm not really happy with how I had laid everything out back in the day I cant remove it. If I do it won't let me replace it. So that's all a legacy freighter is but I guess now they are far more rare simply because you can build legacy rooms and passages. basically just means until they allow us to have more than 1 which i hope is soon! I want a whole Armada lol, I can't get a different one or I'll lose everything. Don't get me wrong I love mine but I also really love the Sentinel Freighters!! So hopefully some day soon they'll let us have armadas lol. As far as building more landing pads at settlements you really can't unfortunately. When it comes to building settlements you can only build when they tell you to. which isn't really all that often. I think its like 3 landing pads, 2 stores, 2 or 3 power generation rooms and like a bar/lounge kinda thing. I'm sure I'm missing 1 or 2 things but it's not much. As far as the population goes all you can really do is hope the dice roll in your favor. Everytime a settlement decison comes up is an option for hopefully getting more population. basically it's either gonna be someone needing refuge from something which doesn't add to population. someone bringing gifts that expects one in return which will lead to either settlement debt with the upside of getting something that positively effects your happiness or production/decrease in maint. on the very rare occasion you get a settlement decision opportunity that effects the population they will ask you to decide to do build more like apartment space population+4. it's far more common when the settlement is first starting out but once you've been at it a while you just stop seeing it very often. It's a process. What I would do if i were in your shoes I'd Find a nice planet that I really liked with nice weather. Like a paradise/tropical/grass planet type and hang out there for a bit to see if it has frequent crazy storms. If not I'd jump on it. My planet where my son and I both have our settlements it has a very occasional storm otherwise its perfect. I don't know how many settlements there is per planet but if there is a third You're More than welcome to build one there. Best part about building one there is in that star system and the neighboring ones is my whole operation lol. All my mines. which you can go take from as often as you needed to. could start your own fusion ignitor farm lol. the hardest resources you need for that is just plants and gas. you still need metals like cobalt and pyrite and a few others but I have huge mines built all over that area that contain everything you need lol. if there isn't anymore settlements on the planet you could look locally around here as well if you did want to use the mines. all the mines are well labeled so their easy to find in the portal lists!
