They still have a lot of hand crafted content, though. There are definitely some things that don't have the intense attention to detail, but it's not No Man's Sky where it's overwhelmingly procedural and randomly generated with very little that stands out.
Some stuff should feel slightly repetitive. There are military and other heavily planned facilities, and those types of organizations would genuinely be standardizing a lot of things for cost and other reasons. They really would reuse base designs for small to medium buildings in worlds where the parameters were similar and they didn't have space constraints. Earth feels organic because of how much less advanced we were when all of those areas filled in, and how many cities were already crowded with people before they decided to build modern stuff.
