Rimworld is a great Colony Sim if you love the idea of Dwarf Fortress but want a gameplay experience that’s much more accessible with a much softer learning curve.

It plays into the chaotic post apocalyptic Mad Max style hellscape fantasy really well, and does not attempt to police your morality. You can love and care for your colonists, meeting their needs and growing to know them as individual people with their own unique stories, or you can play as efficiently or sadistically as you like, throwing ethics out the window and following the Geneva Suggestions wherever you deem prudent.

The base game is good for hundreds of hours of play, and expansions bump that up to thousands of hours of fun, but it also has a very healthy modding community if that’s still not enough.

If you’re unfamiliar with the Colony Sim genre, the basic idea is that you start with a set of semi-randomized colonists on a randomized map and need to build up a functioning Colony to survive. You the player take the role of a manager or overlord and set tasks for your colonists to complete, which they then take time to carry out while you watch and plan the next set of tasks. You need to gather materials, build shelter, grow or hunt food, defend yourself from wildlife and raiders, and recruit new colonists.

Rimworld in particular has fun building mechanics with an emphasis on building power grids and heat management (air conditioning and heating to keep your colonists comfy and keep food from spoiling). It’s a lot like a top-down Oxygen Not Included, but with simpler mechanics and more focus on its (procedurally generated) story.
