Stripped Down for Parts: Cuius Regio: The Thirty Years War, 1618-1648

 

I was really in two minds about writing up an unboxing of Cuius Regio: the Thirty Years War, 1618-1648 (GMT Games. 2026), not because I didn’t think it warranted the attention, but just the opposite; I expected much more excitement than the game has thus far received. With the new shipping set up for P500 orders, where I used to sometimes receive GMT preorders a week or so before my North American friends, they now arrive a month or more later. (I’m not complaining – it does mean the shipping comes out about half or less of what it would coming from the States.) But in that time, there hasn’t seemed to be a lot of interest in the game - except from the usual suspects (Ardwulf's Lair, Kilroy Was Here, Pushing Cardboard and Justegard all produced good unboxing videos – I’d recommend taking a look at any or all of these for a better look at the components close up). When my copy arrived, I admit I got a little excited, and I think I have something to offer for the conversation, so here we are.

The cover features a rather dramatic representation of the double-headed eagle of the Holy Roman Empire, one of the antagonists during the war, superimposed over a classic battle scene. The illustration was prepared by GMT stalwart Kurt Miller. Try as I might, I’ve been unable to identify the painting on which the cover is based; it looks familiar, but I’m not entirely sure the battle depicted is actually a situation from the Thirty Years War (given the uniforms, maybe the War of Spanish Succession, but I’m no expert). If I can get to the bottom of it, I’ll drop in some detail with an edit note.

While it doesn’t give much away, the cover is compelling. The orange, umber and rust tones hint at the ferocity of the conflict, which was responsible for – by some estimates – as many as eight million deaths, either from direct conflict or indirectly from famine, disease and exposure. While I don’t think this would have been my choice, I think the illustration works to attract the interest of the casual shopper.

The box-back.

The box back, to my grognard-gimlet eye, is even more compelling. It features a part of the game map in the top half, with a straight forward description dealing less with the historical situation and more with the basic functions from the game, highlighting some solid selling points; operational/strategic level (with one-year turns), a range of scenarios (five in all, including the full campaign), and some nice, simple counters, Represented at their actual 5/8” size, as well as the aforementioned map.

The scale of the map is sixteen miles to a hex, the units represent something like 500 to 1,000 troops and as mentioned, each turn runs to a calendar year (which makes sense, given a campaign year would typically run from around March until the antagonists took their winter quarters). The graphic data informs us that the game is designed for two players, that the difficulty is reckoned to be five out of nine (middling, though a veteran GCACW player would probably scoff at this), and the solitaire suitability is cast at six out of nine (no doubt due to the hidden information factor at play, but we’ll get to that shortly). It should come as a surprise to no one that the recommended age for the game is fourteen years and up. The box back also informs us that the play-time should be between one and six hours (scenario-dependent) while the full campaign might take thirty to forty hours to play out. This makes Cuius Regio a good candidate for a five- or six-day convention that you can learn before-hand playing shorter scenarios of an evening leading up to the event.

The Rulebook is printed on the familiar, medium weight matt-finish paper GMT has been using for every game I’ve seen of late. No complaints there. The rulebook runs to 24 pages but only 22 of them are printed – the last two are blank (or at least free of game-related information).

Sample Rules spread.

The cover page features a thorough Table of Contents. The core rules – including the introduction and component breakdown – take up the next nineteen pages, with the final two pages given to a page of Optional Rules and a Glossary. At first glance the rules look clear and helpfully illustrated. I don’t anticipate any problems here.

A lot of online discussion has brought up the similarity between the "feel" of Cuius Regio’s play being similar that of games from the Great Campaigns of the AmericanCivil War. It turns out there’s a reason for that. I had cause to correspond with designer Francisco Gradaille regarding another post I’m writing, and he mentioned when he was thinking about the framework for a Thirty Years War game, he happened across a podcast comparing various operational level ACW games, including the Great Campaigns series. Mr Gradaille wrote, “After listening to that, I thought that the manoeuvres during the Thirty Years War had some similarities, and I started searching for wargames that let me have that kind of experience in that period. As I didn’t find any, I decided to make one myself.”

The Scenario book shares all of the physical attributes The scenarios are laid out simply and are immediately comprehensible. The scenarios themselves are broken into discrete campaigns lasting two to thirteen turns, while the full campaign covers the full thirty-one turns.

Scenario 3: The Danish Intervention. Everything you need for each scenario
is presented in a single spread.

The Scenario Book also includes a nine-page Extended Example of Play, three pages of Designer’s Notes, a page of Tips and Tricks for new players, and a page-and-a-half Bibliography that I for one will be scrutinising in depth.

The map as it comes out of the box.

The game map is in two parts (northern and southern). The components list says the game comes with two 34” by 16”, which isn’t quite true. The maps together come to a size of 32” by 33 ½” (with about an inch and a bit of overlap). The play area is very attractive, rendered simply with a buff background with easily recognisable geographical features, and a graduating system of Minor, Major, Great and Electorate Cities, represented by cameo illustrations taking up the entire hex. The rivers and provincial borders conform to hex edges, and the roads run precisely from one side of a hex to another; the whole map is rather schematic, but it really doesn’t feel so. Cartographer Nicolas Roblin has managed to create a map that is at once visually pleasing and eminently playable.

The map complete. Apologies for the glare lines, but this was taken without the benefit
of any flattening technology.

The field of play runs from the Baltic coast in the north to the border of the Swiss Confederacy in the south, and from Poland and Hungary to the east all the way across to the Eastern most provinces of France and the Spanish Netherlands in the west (Rhenish, Lorraine and Franche-Comte are caught up within the playable area). The map also features a Turn Track, and numbered tracks at the top and bottom of the combined sheets, presumably to aid in tracking movement point expenditure for each player’s forces.

Counter sheets 1&2.

There are three sheets of counters. These are printed on the familiar brown-core cardstock GMT has been using for pretty much everything of late. The first two sheets are mainly the available forces of the two sides represented (yellow for the Holy Roman Empire, blue for the Protestants. The troop counters are particularly nice, simply rendered with a single figure and numerical value representing the unit’s strength. The Infantry are represented by arquebusiers, the Cavalry by mounted riders, and the Artillery Trains by a manned cannon. Artillery Trains don’t possess a fighting strength of their own but offer a modifier to the overall combat value of the force.

Counter sheet 3.

Leader counters – Marshals and Lieutenants, are named characters from the Thirty Years War. Each counter features the leader’s name, a rating (1-3), a tiny cameo portrait and the years in which they were historically active. The admin counters are also simple, easy to read at a glance, and pleasing to look at. Army markers are used on the board when playing with the Fog of War optional rule. Markers showing relevant national flags (or in the Imperial case, the Imperial crest and Spanish flag) identify the deployment locations of various armies on the map, and counters with the two-headed eagle on one wide and the Tudor rose on the other are used to indicate control of cities by one or the other side.

There are no less than four Player’s Aid cards included in Cuius Regio, each presented in duplicate (no sharing necessary), doble-sided, and of a single panel, collectively covering all the charts and tables one could possibly need during the course of play. The PACs are not numbered, so I’ll just go through them in the order that seems most sensible.

The first offers a detailed – but not exhaustive – Sequence of Play, and a brief explanation of how Movement Points are calculated for each army. On the reverse of this card is the Terrain Effects Chart (TEC), which explains the diverse terrain and locations featured on the map, and explaining their impact on movement costs and possible influence on Combat

The second PAC is one of two that deals with combat The front offers a sequence of play for Battles with a list of Battle Modifiers and a Odds Modifier table, The Reverse of the card presents the Battle Results Table, which incorporated the table for Modified Battle Results and for the active army’s Fatigue Roll, as well as instructions for the Leader Loss Check, and a Route Check table.

The next PAC deals with Cavalry in combat, featuring a Reaction Move / Cavalry Retreat Before Combat Table, and a Stragglers Check Table. The verso changes subject from Combat to real estate. The Cities table advises on the City Size Value of differing sizes of cities, and the minimum number of troops necessary to gain control of an unoccupied city of that size. The City Control Table is used for establishing control over a city when the army lacks the strength to overwhelm the city outright, and Provincial Conversion Check table declares with a roll (adjusted with any relevant modifiers listed below the table) when control of a province is gained by the player. The title of the game is drawn from a maxim of the time, Cuius regio, eius religio, translating literally to “whose realm, his religion.” Whoever rules the land gets to dictate the land’s religious affiliation.

The final PAC is a bit of a miscellany, collecting the reference tables that didn’t fit elsewhere. The front offers the Marshal Availability Chart, a long list of the number of marshals available to each side in a given year (through the thirty-one game turn/years), the Artillery Cost Table spells out the cost in Political Points (PP) of managing Artillery Trains for your armies, and the Hex Supply Table, which dictates how many troops may be kept in given location during Winter Quarters (i.e., carried over from one campaign year to the next). The verso presented the Province Control and Reinforcement Table and the Troop Purchase Table. The Province Control and Reinforcement Table offers an alphabetical list of all the provinces present in the play area, whether a province might be persuaded to flip religions and the difficulty in that venture (DRM), the number of cities that need to be controlled before control may be achieved, and how many reinforcements the province may provide when under a faction’s control

All the PACs are elegantly laid out and very easy to navigate and read. I like the idea of not having to constantly open a bi- or tri-fold PAC to find what I’m looking for at a given time, and I think the use of these will become second nature after a few full turns of a game.

The Army Boards. The game's colour palette is one of its many strengths.

Each faction’s armies may be all out on the map, or alternately, they may be managed on that side’s Army board, with an Army marker indicating each army’s location on the board (these are imperative for use with the Fog of War optional rule). This is a single-sided card-sheet printed on the same weight card as the PACs, with spaces for up to five separate armies, an Active Leaders Pool, three spaces for the activation markers used to indicate the number of Lieutenants activated in the current turn, and a ten-space tally chart, running 0-9, like the ones printed at each end of the play map.

The Shields depict battles from the Thirty Years War.   

The Army boards may each be concealed from the prying eyes the enemy with the use of a shield, two of which are provided in the game. These are constructed using the same weight of card as the PACs and Battle Maps, stand at a low enough height for them to be perfectly adequate for the task of screening a faction’s Army board.

Shields deployed.

-----

So, that’s what you can expect in Cuius Regio. It’s a really nice-looking game that promises an interesting play experience but is probably fated to receive nearly the audience it deserves by dint of it not being a more popular subject in the English-speaking world. Which is a shame in itself, but that’s a subject for another time. I look forward t playing this some time in the future. At this point, my meagre ambitions extend to hopefully tabling the game before the end of 2026, a goal I hold for several other games as well, but Cuius Regio might just be moving to the top of the list.
