RimWorld [Official Site, Steam], the colony building simulator has a massive alpha 16 update named 'Wanderlust' and it's truly huge.
Generated worlds are now sphere shaped split into hexagons and pentagons along with better world generation. You can also now travel across the world, which changes how the entire game feels.
Maps in the game run at the same time, so your home colony will be active and running at the same time as you doing something else in the world. That's really cool and shows how massive the simulation in this game is!
Time of day is modelled on the planet view, so an area where the sun hits has daylight for example. So a proper day and night cycle essentially!
A new way to end the game has been opened, as an NPC may offer you a ship, but it will take a long time to travel there. This comes with plenty of encounters to deal with.
See the rather long update notes here.
I've played plenty of this game and highly recommend it!
