I always put an aquarium for any fishes I collect, at least 10 lockers because I’m a storage junkie, an interior growbed with lantern trees, and basic normal-base stuff like a fabricator or radio.
A bed, fabricator, 25 storage lockers (the big ones), Med kit fabricator, two farms, modification station, a markiplier doll, and enough materials to rebuild the entire subnautica map four times
