While the focus in RimWorld is on the stretch of land that you’ve claimed for your base, the entire planet is available to you to explore. You can see the spread of different biomes and factions when you select your landing site at the beginning of the game, but really exploring and interacting with the broader world is dependent on either sending out risky caravans or developing later-game technologies like drop pods and (now with Odyssey) gravships. For our System Hack, the base site is likely to feel a bit smaller, and venturing out onto the world map is something that happens sooner. Luckily, we have decades of wilderness exploration in TTRPGs to help us out. When looking at our overworld map, we want to make sure that exploration and venturing beyond the base site both provides interesting decisions and helps us populate a world with people and places that our players will want to explore.

The overworld is also where we start considering some of the setting assumptions of RimWorld, and deciding where we converge or diverge. RimWorld’s implied setting is fascinating, but the place where all of the setting ideas fail to emulsify is in the overworld. Beyond the dispersion of settlements being a clear game contrivance, the lack of any population buildup or agglomeration is just not how any planet would look after years of colonization. There is a line to be walked here; a ‘RimWorld’ would likely self-select for individualists who may want space and to be left alone, but there’s simply too many personal and economic benefits for larger settlement to assume there wouldn’t be any.
