RimWorld

- The little automated gun emplacements aren't that strong, but enemies prioritize them so not only does it help control the places your enemies attack, it keeps your colonists alive a little longer.

- With pod crash landings, 'rescue' means they leave after you treat them, to keep them in the colony you have to capture them and convince them to stay.

- Horseshoe posts are cheap and train shooting.

- Make sure to change the selected material when building. My first colony was made of a lot of steel, and early on, steel is valuable.

- 5x5 rooms with only a bed are just big enough to avoid negative moodlets for being cramped.

- Hauling is a huge time sink, so be thoughtful about stockpiles. Having a priority stockpile set at a high priority near a crafting table will save a lot of time in the long run. Similarly, make sure it's a short walk from your fields to your fridge.
