I think I've started on a new level of Rimworld war crimes. I started a save with the new oddysey DLC. I set up a vault colony inside the new urban ruins biome. There's a giant toxin vent outside that occasionally spits out pollution when it feels like. I think I can outlast any sieges due to the fact they'll probably be dying of breathing carcinoma fumes, if they try it at the wrong time, while my colonists stay safely inside just eating mushrooms.
Edit:
Fun fact lol: it's literally so toxic that animals that stick around in the area for too long during these eruptions, become unfit for consumption and start rotting immediately once hunted.
It warms my heart to see them yelling at each other and having fun. I prefer perfect dark, but there is a lot of fun to be found in the raw simplicity of goldeneye
