So we have 2 policies for infrastructure, one of which is doubled, another from the law, giving us at least 3 progress on any given turn.
1 policy for vassal support, 1 policy for defense, 1 policy for forestry, and 2 ??? policies.
We have two True cities IIRC, two Free cities? 2 +4 = 6 policies.
Both of the "player" infrastructure policies are doubled, only the "auto" one from the law isn't, so we get 5 progress each turn right now.
We have 1 Vassal Support, 1 Defense, 1 Forestry, and 2 Infrastructure policies chosen, for a total of 5 player policies.
We currently have 4 active true cities: Valleyhome, blackmouth, redshore, and redhills. Free Cities count as true cities for most things.
We get passive policies from our economic system, Guild Mercantile, as shown on the civ sheet:
"Passive Policies: 1 + True Cities (includes Free Cities)"
That is, 5 total at the moment.
Then, one of the inherent benefits of Free Cities at our tech level (along with "remove base 1 econ/turn upkeep" and "remove the normal true city -1 high cent tolerance penalty") is that they give an additional passive policy according to their "AI", which seems to be
mostly about the overall picture of the civ as a whole, but with a bit more focus on the cities themselves (i.e. they started out making baths and libraries for themselves, but also took some innovation policies and martial policies to benefit the overall civ)
Then, due to the choices we've made for megaprojects, we have 1 Infrastructure policy (from the Iron Age Law, which is not doubled by the law bonus like player-chosen infrastructure policies) and 1 innovation policy (from the Artisan Games, which
does get the benefit from the AG, that being doubled innovation rolls at the cost of 1 wealth)
Balance? Its just what AN decided the benefit of the Iron Age Law (with "Community Health" Focus) should be:
"New effects: player chosen Infrastructure policies doubled (one action only for active policies), one additional passive infrastructure policy always active (effect not doubled), -1 Wealth each turn."
Edit: But yeah, i'll try to remember to add in passive policies to my infrastructure tracker next update.
