Also want to second Against the Storm, with the caveat that if you enjoy seeing your colony go self-sufficient, this isn't really the game. The instant your colony goes self-sufficient here, the game is basically over, and the gameplay loop consists entirely of the struggle in getting there based on a randomised set of variables.

... which makes it my favourite colony sim by a mile. I think I have over two hundred hours in it, and it's still getting improved by the active devs.

It's my most played game this year and I was just doing the Beaver Utopia achievement a while ago today.

But it's not really a colony management game in the same sense. It's more of a roguelite-ish city builder.

Against the storm is one of my favorite entries to the sub genre in a long time. I play loads of city/colony sims and this title stood out as something unique without getting away from the core elements of a colony sim. It also takes the best parts of rogue likes without making the game feel impossibly hard (but you can ramp up the difficulty in a variety of ways including in the middle of playing)

But like others have stated it's not going to scratch the same itch as massive city builders like Cities, or factory games.

Still it felt fresh and I dumped a couple hundred hours into it already.
