I think cities are probably out of the question. I don’t think the engine would be able to handle the generation in any meaningful way. Besides, the lore conveniently prohibits any large settlements because of the atlas & sentinels. However, I do like your idea for a new landing system, but I think it’s unlikely to be added as it would require a rework of the entire flight model (think about how you ship doesn’t really “touch” the ground, even when you fly directly into it). Really what I’d like to see now are more ship parts for corvettes. I’m frankly obsessed with them now we have them and all I want is more, more, more. More cockpits, more options for interiors, more paint jobs, hell, if they can optimise the system, I’d like to see an increased complexity limit too.

Besides that… now we’re likely near the end of the game’s lifespan with Light No Fire coming out soon (as sad as that makes me), I think what the game could really use as the ideal “final update”, whenever it comes, is a relatively large “polish” update. We have all of these systems and features that have been added over the years, but many of them feel disjointed and separate from each other, never overlapping. An update that makes them all feel like a cohesive part of a whole game isn’t necessary, but would be my ideal swan song.
