Hi everyone - Ty here.We’re loving your Anomaly stories! Please keep it up with the duplicated babies, shambler babies, and gray labyrinth baby drama. This expansion explores new ground creatively for RimWorld and it’s been incredibly gratifying to see people having new kinds of stories in the game.Releases like this bring massive amounts of feedback, which is always incredibly valuable for us to understand how the game is playing and what people want. This time around, many players have said they’d like to be able to mix Anomaly content more into the rest of the game so it feels like less of a self-contained experience, and more like something that integrates into a normal playthrough.Originally, we had Anomaly throw a ton of content at you guys because we wanted to be sure people would experience all the new stuff and see how much was really there. We may have pushed a bit too far there - Anomaly has tons of content and exposing it all too fast was saturating the experience. This is ... Read more
