Rimworld is probably one of my favourite games. I highly recommend it to anyone who is interested. This new expansion also seems really cool, I copied two points from the steam description that stood out to me(spoiler warning! Hopefully most lemmy clients support spoiler tags):

:::spoiler

A psychically-invisible hunter of human souls screeches outside your walls, returning every night to capture a new victim. The proximity alarm goes off, but you can’t see the beast. Study samples of the creature to learn to detect it. Then, become the hunters and kill it where it lives.

A parasite has mind-controlled some of your colonists - but who? They pretend to be human as they work to infest others. Track evidence, imprison, interrogate, and medically test people to find out who is infested before it’s too late.

:::

That being said, I’ve only played the base game so far, and I think I’ve always played on the difficulty that is just one above peaceful, and I found it really hard near the end. But I’ve never bothered with killboxes, and I keep my colony wealth high I guess, I like to hoard food, silver, and everything. I also build floors (some people skip them to keep their wealth low). Perhaps I should have added: raid strength depends on your colony wealth (I think).

Does anyone have any tips for actually reaching the end game event? (Please use spoiler tags! I know a bit about it, but I think many people like to be surprised. Put :::spoiler before and ::: at the end.)
