I'm looking for a new colony sim on PC. What I've played so far are:
Rimworld
Oxygen Not Included
Banished
Timberworld
Frostpunk
Anno 1800
I know some of these might not be strictly colony sims. What I'm really looking forward to is Manor Lords, but we don't have a definite release date on that.
Ixion comes to mind. You are in charge of managing a space station as you try to navigate the last of humanity to a new planet. Its more directed than most Sims, with a campaign split in to multiple acts but I found it quite challenging and engaging.
You know... I was enjoying playing this until an unfortunate turn of events led to my people going hungry. They then chose to go on strike, but only in the places that produced food... (╯°□°)╯︵ ┻━┻
Yeah I was in the same boat. Things can go bad very quickly. I think the game expects you to hang out in each chapter for a long time and really optimize your station. It's HARD.
I heard they improved the difficulty a little with a recent update but I feel like the ship has sailed for me. I may come back to it sometime because I found the story really interesting.
