Rimworld is a video game that allows the player to control their colony in any way they want to, as well as handle the consequences. You can try to wipe out every other faction in the planet, but you'll have to plan well since not all of your colonists will survive. You can try to play peacefully, but not every human wants that, and that's not even going into the mechanoids and insects.
Although you are supposed to leave the planet usnig a starship, I decided to exploit this freedom and do a challenge run in which I'll just commit as many war crimes as possible (or do you spell it like warcrimes?), using the definition from the UN (https://www.un.org/en/genocideprevent.... It's ok to violate human rights in a game, yea?
Good thing this didn't need me to escape the planet. God forbid I finish the games I play.
