Alternatively, items can also be stored outside in shelves. Now, most items will start rotting if they are not stored covered under a roof. This savegame is from an older patch, back then it was still possible to store all items outdoors. If your colonists are in the dark for too long, they also get debuffs.
So far, there is little to no light in the whole base. In the beginning, many things are anything but optimal: The colonists do not have their own sleeping rooms, so they are often disturbed by the others while sleeping and receive mood debuffs. In my first actual play through of RimWorld I built a mountain base, which means I nestled in an existing cave system. The start was very unstructured, many things I would do differently now. But even if you think you've got everything under control, there is that one pyromaniac who thinks it's fun to play with fire close to the power generators. That's why my first colony was not the very first, but the first that made it. Especially as a noob, one thing that the game keeps offering to you are creative ways to kill your colonists. In the beginning everything is a process in RimWorld. In this post, I'll show you one of my first colonies, what can go wrong and tips on how to do better.
