I don't know why exactly, but when I woke up at 3:30 in the morning and couldn't get back to sleep, I decided the best way to spend this time was to start up Citizen Sleeper. And you know what? It kind of was. The darkness outside, the darkness of space. The chill, electronic swirls and pings of the soundtrack. The (mostly) relaxed gameplay loop, essentially a visual novel with light RPG mechanics. A game you can sink into, like a dream. Perfect for the wee hours of the morning when the world outside is still largely theoretical.
So then when I woke up at 3am the next day, I figured why not? After which point, the idea of playing it during any other time of day felt...wrong, somehow? Like the spell the game had me under would break in the sun and I'd never be able to put it back together.
Now, I can't really recommend only playing this game between the hours of 3am and 6am. But having done exactly that, I can say that if you find yourself regularly being awake during that time, Citizen Sleeper is a pretty good fit for it.
Let see, what else. Art: beautiful. Music: immaculate vibes. World: Fascinating. Characters: richly-developed. Story: all heart, no filler. And the premise is so much more interesting than what I thought it was going to be. In short, if you have any interest at all in text-driven sci-fi about defending (or, indeed, redefining) your humanity against greed and exploitation, this is the perfect game for you.
p.s. Some advice for the late game: Once you've dealt with the main countdown clock by either getting protection or destroying your tracker, try to avoiding doing to many missions at once going forward. Several of the missions can affect what resources you have access to, and a lot of them will have timed clocks at some point, and having too many of those going at once can be incredibly stressful. And when the game says the flotilla missions are intended for late game, they really mean it. I'd suggest completing everything else before even starting those, because they require a lot of focus, and narratively will assume that you've completed most of the main character arcs.
p.p.s. I think beyond just the chill vibes and the sprinkle of pre-dawn magic, there's something about the fact that, depending on how you play, you can go pretty much the entire game without doing any work that you don't want to do. Whether it's paying back the scrapper who rescued you, or tending bar for one of the first people to show you real kindness, or working the land of the commune because it feels good to take care of others and be taken care of in turn. There are very few jobs in the game that you do simply to survive. I think some of the magic of the game comes from being given the opportunity to devote all of yourself, not just a fraction, to living a meaningful life, and to have that devotion still yield the resources you need to keep living.
