| By God Alone Dev Diary #1 - Tenets & Spiritual Fulfillment | 2026-04-28 | Happy Tuesday, and welcome to our first official dev diary for our upcoming expansion By God Alone! In our sneak preview, we gave you the grand tour from the mountaintop. This week, we're going to zoom in on one particular slice of the new expansion features, where your character starts having an actual relationship with their faith. This is the foundation upon which many of the features we'll discuss in later dev diaries are built.We will look over our revisions to Tenets, Spiritual Fulfillment, Personal Tenets, and the new Study Faith scheme. Along the way, I'll walk you through the reworked Faith UI, which is where most of this comes toget |

One that, every now and then, does not crave power or ceremony at all.Sometimes, all he truly wants is a hug.Inspired by the All Under Heaven expansion for Crusader Kings III and made in partnership with Makeship, this Emperor Platypus plushie embodie |

| Dev Diary #192 - Spring Cleaning | 2026-02-17 | Heya y’all! My name is Riad. You may know me as the QA guy who sometimes posts on Reddit, or the guy who showed off the Black Forge Jam projects last year… or, more recently, the guy who wrote that apology. Yeah.Since then, a lot has happened for us at Studio Black. We released our biggest expansion ever, All Under Heaven, which added many long-missing parts of the world to Crusader Kings III and, at last, completed what we consider to be the full map of the game.We were genuinely blown away by the response from the community after release, both in terms of enthusiasm and the sheer volume of feedback we received.

| Dev Diary 191 - 2025 in Review | 2025-12-16 | Greetings! I'm Alexander Oltner, the Game Director for Crusader Kings III.Another year has passed, and the game grows ever larger! Before we look back on 2025, allow me to look back to 2017 for a moment! A mere two years after I had started working at Paradox, we released Jade Dragon for Crusader Kings 2 - an expansion that was somewhat of a compromise between adding Asia and not adding it. I remember designing systems of tribute and grace, where you could request various things from an immaterial off-the-map version of China… with a ‘western protectorate’, and a very artificial invasion of China acting as sort of an end-game boss for player |
