RimWorld

RimWorld is an indie top-down construction and management simulation video game by Montreal-based developer Ludeon Studios. Originally called Eclipse Colony, it was initially released as a Kickstarter crowdfunding project in early access for Microsoft Windows, macOS, and Linux in November 2013, and was officially released on October 17, 2018.

The objective of the game is to ensure the survival of a colony of people, fighting against various environmental and/or internal events. Much of the difficulty as well as the critical acclaim for the game come from its unpredictability, through randomly generated events, and its extensively designed and customizable world. As the game progresses events become progressively harder and the player can unlock more advanced technology through research. The game has a top-down, two-dimensional view.

Events can be good (for example, a wanderer joins the colony), neutral (travellers passing through the area) or bad (a pirate raid, solar flare, etc.). When choosing a story teller the player also chooses what save mode and difficulty to play on. There are 6 different difficulties ranging from peaceful to merciless. These influence the severity and frequency of events as well as the good, neutral, bad balance of events. The game also has two modes for saving the game that needs to be chosen. One mode, called commitment mode, only lets the player save and exit the game making the choices made for each random event permanent. The other mode allows saving and loading anytime during the game allowing the player to experience multiple ways to respond to the event given.
