In reply to inthesomeday and building on their proposal:
I like how you defined and explained the different types of civics and I really like that you have pretty much kept to single dimensions for each of your categories. Other proposals mix different dimensions for each. Here each civic option is more of a policy or state and not so much a system by itself. To give a quick example, a hereditary monarchy (one of the earlier government civics) describes the transfer of power (hereditary), the consolidation and residency of power (a single ruler), and implicitly the source of sovereignty (the crown, probably as a divine intermediary), in a way that is historically relevant and synergic. I mean, this existed or exists and this combination of institutions worked together well. In inthesomeday's proposal, and also here, these functions are separated and the player would have greater flexibility to mix and match them.
I like how you explained the different types of administrative civics and I really like that you have pretty much kept to single dimensions for each of your categories. Other proposals mix different dimensions for each of the categories. While this adds consistency, it also leaves many potential civic options out of the game. I'll point out some examples in my post, as I discuss my observations and proposals on it.
A general comment might be that I don't like the generic "starter" civic for each category, especially because system does not follow a linear chronological progression, but rather choses different dimensions to distinguish types.
--------------------------------
Political System
You have broken down the political system (of the State, not of society) into three parts: administration, government, sovereignty.
About Government
You defined government as "the de facto composition of the highest authority" and include monarchy, oligarchy, parliament, democracy, and bureaucracy, but these rather seem to be different structures of power consolidation, different levels of power sharing, or we could even define it as the institution where power/sovereignty reside (where they reside finally, not necessarily where they comes from).
Here I find bureaucracy to be the odd one out, as a bureaucracy is the State apparatus, the institution by which administration is carried out, regardless of the form of government. With the exception of ancient Greece, I can't think of any real direct democracies. Switzerland today acts in some cases through referenda, but normally it has an representatives making decisions. Moreover, democracy as we use the word today rather defines the source of the power, not its final place of residency. So perhaps replacing it with "Presidentialism" is a better word choice. In this sense, Parliament I'm assuming stands for Parliamentary Republics, where parliament/congress is superior to the executive, with Presidentialism being the opposite. This gives the following: Monarchy, Oligarchy, Parliamentarism, Presidentialism... with one empty slot. Some form of pre-monarchical rule could be the option here?
About Sovereignty
You defined sovereignty as "the origin of the power" and include despotism, religion, popular, meritocratic, hereditary. I agree with your definition for the category.
However, I don't think meritocracy fits with the others. The term is normally associated with the election of state officials. In this sense merit is not the source of power, but a means of receiving power from the recognition of existing power structures. So power is not inherent to merit. Hereditary is also not a source of power, but just a mechanism to transfer it. In the case of monarchies, the source of power remains the Crown, not the family lineage itself.
Actual sources of sovereignty can be: Force (we can think of military governments or perhaps the leadership of the khanates), the Divine (including most monarchies, but also theocracies, and perhaps islamic republics), and the People (which technically includes communist and democratic regimes), but at least now I can't think of any other... perhaps what's left out is economic means, including everything from land to wealth? However, it's not as well fitting as the other three, as these economic means are usually converted to force (paying for armies) or used to corrupt, but they're not themselves sources of sovereignty. In any case, there would be two empty spot.
About Administration / Territory
I think that here you don't mean how the government is run (as you said), but rather you describe the power relationship between the component territories of the political entity - maybe the category should be renamed to "territory".
Here I find the inclusion of totalitarianism not very worthwhile. Empires, Confederations, Federations, and Unitary States are all distinctive forms of government that describe the relationship between the territories. I agree that Imperialism fits well to Russia, and I'd extend that to China. To replace totalitarianism, we could think of something that describes Colonial empires that had viceroyalties, like the Spanish Kingdom, or like the Commonwealth - where the viceroyalties where not entirely on par with the main state, but also had some degree of autonomy and where subservient to the crown (the head of state) but not to the government itself..
A fourth category: Administration
With former "administration" renamed to territory, we could think of how the government is run - the use of appointed officials, favoritism, professional civil service, etc., comes to mind as potential ideas here, but more thought is needed there.
--------------------------------
Economic System
You also have broken down the economic system in three parts: labor, trade, and economy (the latter could be renamed to production, but perhaps should be changed).
About Labor
You defined labor as the way the workforce is organized, but you seem to refer exclusively to the organization vis a vis the elites (ie, not internally), so for clarity we could talk about the type of contract between the workforce and the elites (or, as you say, where subservience comes from). You have: Communal, Tributary, Voluntary, Feudal and Artisan.
I understand communal as collective organizations (where there's joint ownership of the means of production). I find some conflicts between voluntary wage labor and artisanship (as you defined it), as they're basically both voluntary labor with money as a means of exchange. In one case money is exchanged for labor itself and in the second for the products of labor. I find a similar conflict between tributary and feudal systems, in both there is an allegiance or moral duty / debt that makes for the exchange to happen. If these distinctions are enough to merit these being separate civics, I guess that's fine, but I'll also try to think of other possibilities.
A proposal: "Self-employment" (including self-subsistence farming) should replace artisanship. The word "employment" should replace "voluntary", and "collectivities" should replace communal (as this way it includes agricultural collectivities, but also worker ownership). We should add "slavery" (forced labor) as a category, and servitude (by which I mean indebted servitude, including serfdom).
About Trade
I note that you define trade as the way wealth flows within and outside the society. Although the definition overlaps entirely with the one for labor (as the contract between the parties already defines the way wealth flows and in the economy category, the creation of wealth also defines how it flows). Your proposed civics are: nomadic, capitalist, mercantile, socialist, organized, regulated.
I'm having trouble identifying the dimension used to distinguish between these. Nomadic, for example refers not to how wealth flows, but rather to unsettled life. Most civs in game aren't nomadic, but for the few exceptions where some part of the population was clearly nomad (Tibet, Mongols) wealth flows were either tributary or voluntary (barter, market exchange) mechanisms. Mercantilism is as much about industry as it's about trade, with both policies geared towards autarky or self-sufficiency. You also described socialist and regulated as a continuum of regulatory intervention where I imagine capitalist is the other end, but I don't know what you mean by "organized". So I see 3 (possibly 4) civics as the most consistent here: socialist, regulated, capitalist, with mercantilism being on a different axis (contrasted to open trade), and nomadic belonging to a completely different category (it seems more like a "social" civic). Within the first three, better words could be found: perhaps Controlled, Regulated, Free, could do it, these apply both to domestic and international trade. "Socialism" and "capitalism" as concepts rather describe ownership of wealth and/or means of production, not so much their flow.
I also note that your definition of trade excludes the means of exchange (so banter / money are out of the question as potential civics) and the ownership of the trade system (who decides what to trade? - a self-employed merchant class, the State itself even if through intermediaries, and large corporations and trading companies could be a third option here).
About Economy
You define the "economy" category as the way society produces its wealth and resources, renaming it to production could make more sense (as labor and trade are technically also "economy"), although I think we should scrape this off, I'll explain next. Your categories: agricultural, manufacturing, pastoral, commercial, and plantations.
It seems the guiding principle of classification is the state of development in terms of primary, secondary, and tertiary activities - you can also say the state of industrialization. Agricultural and pastoralism are basically on the same level here, with plantations next (it's implied that this is large scale agriculture geared towards trade), next manufacturing, and finally commercial. The main problem I see is that these aren't civics per se, they're definitely not policies that can be chosen by governments, but rather states that result of the comparative share of economic activity going to each sector. In this sense, I can see the game calculating your degree of industrialization in the stats page, but not so much it being a civic. I suggest to remove these civics altogether.
Instead, we could perhaps think of
Ownership as a third economic category. It would determine the favored ownwership (and consolidation) of the means of production. How are land, capital, technologies, etc., owned? Options can be: Small companies (incl. family owned and smallholder farmers), Private Entities (in a capitalist way, companies in the Western sense, medium sized, etc), Corporations (also in a capitalist way, but referring to the more neoliberal way including modern corporations and even trading companies), Collectivities (incl. farmer associastions and worker unions) and State-owned.
Another option, closer to what you had in mind, would be the relative appreciation for specific economic activities, or in other words, what's the most
"noble" role in society or the one placed at the center of it all. I can think of options: agrarianism (farmers), industrialism (workers), capitalism (entrepreneurs), consumerism (consumers), militarism or martialism (the army), name? (the priesthood and monks), name? (educators and scientists), name? (social workers including doctors, charities). This would definitely be a
social and not an economic civic, but I would find it interesting for the game. And the civics themselves would have to be curated a bit to reduce overlap and reach 5 options to be consistent with other categories.
