mqstout: Some games I found rather chill when playing them. Not necessarily quite in your genres listed, but maybe you'll want to expand:
https://www.gog.com/en/game/unpacking A reverse "hidden object" game with a subtle implicit/unstated narrative as you complete the levels.
Looks cute and chill indeed, wishlisted.
mqstout: https://colepowered.itch.io/concrete-jungle (sadly not on GOG!)
A superfun puzzle city-builder.
There's been many cool suggestions already, but this one actually intrigued me the most. It's really sad it isn't on GOG, but I still have an itch.io account, so maybe...
https://www.gog.com/en/game/rebuild_3_gangs_of_deadsville A pretty chill turn-based zombie-survival strategy-light game.
This one also looks amusing. Overall design and premise are catchy. WIshlisted as well.
mqstout: https://www.gog.com/en/game/growing_up A "gateway" visual novel that's really chill, allows for multiple plays, and whatnot. The puzzle mini-game in it is neat.
https://www.gog.com/en/game/simulacra It's a FMV-style point and click adventure lite horror game. But the way you explore it is kind of chill if you can handle a few jump scares (and they're not bad one). Again, it's a subtle plot.
https://www.gog.com/en/game/reigns (also has various sequels I haven't played)
Make a series of binary choices to develop your kingdom and live as long as you can. The game does technically have an ending that's obtuse AF to get, and I haven't even after looking it up. But that's not the point of it to me
Nowadays, I try to avoid games that have too much of a "campaign/scenario" component : most of the time, it doesn't hook me enough, and I skim through dialogues, so games based on that wouldn't work ^^'
mqstout: https://www.gog.com/en/game/lego_bricktales A pure explore/collect/light puzzle game
I played that one ^^ It was fun
mqstout: https://www.gog.com/en/game/endzone_a_world_apart Others recommended Banished. This is "post-apocalyptic Banished". It does have occasional raids (basically a tower defense mode) that might count as un-chill for you.
I really feel "meh" about Banished as is, but both it and Endzone fall a bit in the same "sandbox" category ; I play Minecraft already, and it's enough to fill the sandbox itch (by sandbox, I also mean open ended ; I prefer games like Pharaoh or Zeus, that have some puzzle/scenerised aspects).
mqstout: https://www.gog.com/en/game/book_of_demons "Diablo, but with sliders for you to adjust difficulty and session length, and abstracted out a bit."
This really caught my eye, but one reviewer says that it's a bit of a click fest... I love Grimdawn, or Titan Quest, but it's basic enough.
Book of demons sounds basic, but if the mechanic is too clicky, it might not do.
mqstout: A couple that might get in your path that I'd suggest avoiding:
Block'hood
Tinytopia (it might sound like it fits, but the puzzle stages that are physics puzzles are NOT chill and rather frustrating.)
I agree : I tested those, and it really didn't fit. Block'hood was actually kinda misleading too ! The tutorial presented the game in a different way than it ended up playing out. Quite sad.
bjgamer: I tend to like a lot of chill builder/crafting games. Here are a few you might look into:
If you like Pharaoh/Zeus, then try
Emperor: Rise of the Middle Kingdom It was my favorite of the older city builders and it's currently on sale for 50% off.
I second the previous recommendation for
Banished. There are many different maps and combos of farming to start with, lots of mods once you get the basics down, you can play in short segments and save or go for hours, and you can turn OFF tornados or other 'disasters' if you want a totally chill experience. Wait for a sale, it's usually 50-60% off a couple times a year.
I don't know if you are into Open World crafting and terraforming, but lately I've really been enjoying
The Planet Crafter. It's personal base building any way and almost anywhere you like, crafting, terraforming, exploring with some survival (oxygen, food and water) mixed in. It reminds me of Subnautica without the story or creatures (or ocean depths), at least at the moment. Start on 'Relaxing' for the most chill game without penalties. After the first little bit of crafting oxygen tanks, making water from the ice and learning about how far apart to build outposts, the only thing to watch out for is to get yourself indoors or into a cave during meteor showers, which the environmental clues warns you are coming and get less frequent as you develop an atmosphere on planet. Again, you can play for however long you want at a time and save when and where you want. It is Early Access, but totally playable now and currently on sale. Check it out! :)
EDIT- There is currently a demo on Valve's site if you want to try it out first. I don't know why GOG doesn't currently have a demo as well.
I own
Emperor - I own all three games in their glorious box versions (well, Emperor was just a DVD box, but it still had a manual and map). Among my fav games of all time !
As for
The Planet Crafter, like I said above, I have Minecraft that fill the deep open world crafting game. I can't really see myself investing into another similar game, however different it could be otherwise.
AnimalMother117: Not sure if somebody already mentioned them, but the first games that came to my mind were Stronghold 1 and Crusader 1. Castle builder in Stronghold 2 would work as well.
Stronghold Crusader has a castle builder mode as well wherein you just focus on...building a castle and managing the economic side of things. It kind of exposes a certain lack of depth to the mechanics, but I sometimes put it on when I want to split my attention. For instance, if there was a podcast or some such thing I wanted to listen to but am having a hard time staying focused on it.
There's an economic campaign in the first game which makes things a bit more challenging.
I played
Stronghold back in the days. Terrific game. I actually own it here, along with
Crusader, but I haven't gotten back to them yet.
