You could try ProsperousUniverse. It’s more of a game you play while you play others, but definitely a “wait, I spent 18 hours on a spreadsheet?” type of game.

Back in the day, Maxis had an entire brand of “Sim” games that were exactly this. Sim Farm, Sim Earth, Sim Ant, and, most notably, Sim City. I have no idea how many titles there were, but there were a lot of them.

Then EA ate them.

I’m trying to make a game in this genre though I describe it as a base-building/simulation/survival game, other favourites include Oxygen Not Included, Timberborn, Factorio and Satisfactory.

I really love Anno for this, 1800 is the only one I have played and I think it’s an amazing game. The base game on its own has tons of content already but the dlc’s add whole new regions and lots of supply chians to the game. It’s a bit of a crossover between a city builder and a supply chain simulator, where the majority of the game is based on providing the needs for your residents. It’s on sale very often, including the dlc’s.

If you were to get it, I recommend getting the dlc’s, maybe after a playthrough of the base game. If you wanna know what dlc’s to get, you can check out these videos:

I would consider them a few different genres, but they are easily my favourite types of games these days. I cateogrize them in my steam list as below.

-Colony Builders: Games about building well, a colony, often from little to nothing. Often lots of You vs Environment friction, with the natural world. Tends to have a bit more focus on the individuals that comprise the colony. Examples: Rimworld (my favourite game of all time), Dwarf Fortress, Oxygen Not Included, Stranded Alien Dawn, Space Haven.

-City Builders: A bit broader in scope than a colony builder, working more on the macro level. Friction is often economic, sometimes adjusted with the natural world. Cities Skylines is kind of the prime exampe of this, but also games like Timberborn or Anno.

-Automation: Games about building a factory that…builds things automatically. Challenge tends to be logistical complexity but some games do feature combat as well. Factorio, Dyson Sphere Program (my personal favourite), Satisfactory, and Captain of Industry are the Four Horsemen of this genre to me. Techtonica is very early still but seems to have some promise as well.

For many of these games, there is a whole world of content to explore if you are interested in mods. Rimworld players regularly run hundreds of mods, my current game has about 350. Factorio has extensive overhaul mods that can take literally thousands of hours to finish in some cases (Py’s). Satisfactory has a surprisingly robust mod scene for an early access game too.
