RimWorld is a sci-fi themed colony-building game where players manage a group of survivors on a distant planet. The game is known for its depth, complexity, and challenging gameplay. Players must manage their colonists' needs, relationships, and skills while dealing with the harsh environment, raiders, and other threats.

If Royalty is about external hierarchy, Ideology is about internal conviction. This DLC allows players to craft belief systems: transhumanist, tree-connection, raider, cannibal, or any custom hybrid. Pawns now have meme-driven needs. A tunneler fungus-cult despises sunlight; a supremacist colony requires slaves; a high-life commune needs a constant supply of smokeleaf joints.

Ideology transforms every mundane action into a potential schism. When a crash-landed refugee asks for help, do you take them in? For a charitable ideoligion, refusal causes a mood crisis. For a raiding ideoligion, letting them go is heresy. The ritual system further amplifies drama: a failed gladiator duel can turn two lovers into rivals; a successful Christmas-esque “Yulefest” can unite disparate faiths. Combined with version 1.4’s improved social interactions, Ideology ensures that the colony’s greatest enemy is often its own conflicting values. It turns the game into a theological pressure cooker—one where you cannot please everyone because everyone believes different truths.
