Old World - The Sacred and The Profane is a new DLC for the impressive historical strategy game from Mohawk Games and publisher Hooded Horse. I'm actually really surprised by Old World, it arrived on Steam back in May 2022 with full Native Linux support that worked great. Since then, they've continued regularly updating the game with new free content and upgrades.
This new DLC just dropped out of nowhere and it's pretty big too! While it's a historical game, this expansion is more about the "what if". It includes over 350 new events, new clergy characters, 10 new character traits, six new historical characters, new religious dissent mechanics as well as a bunch of "cult" city projects.
If you love 4x style strategy games like Civilization, give it a go.
