After five and a half years of development, Ludeon Studios has released the 1.0 version of its colony management game Rimworld (opens in new tab).
You can watch a trailer for it above—the latest version is "mostly the same" as beta version 19, save for lots of bug fixes and a food restriction system that lets you manage what your colonists and prisoners can eat.
If you've never played before, then Rimworld tasks you with building a new colony in the far future, starting with the three survivors of a starship crash. It's a dense, deep game inspired by Dwarf Fortress, and it simulates ecology, gunplay, melee combat, climate, biomes, diplomacy, interpersonal relationships, art, medicine, trade, your colonists' mental state, and more.
It's full of detail: a character's background will change how they act, and wounds or infections are tracked for individual body parts, which each one affecting the capacity of a colonist.
Ludeon describes it as a "story generator", and where you land on the planet—desert, jungles, forests, snowy tundra—will have a huge impact on your journey.
