Had a few more thoughts about the multi-hex based city idea. Given the patterns hexes fall into, I think the best shape/sizes would be 1 hex (village/hamlet), 3 hexes (town/small city), 4 hexes (city-state), and 7 hexes (metropolis). I wonder if we can break from the granary paradigm we have now, where granaries only increase city population growth. I would think a granary or some other form of permanent food storage and distribution is a Necessity for a city to grow in size/area. A growing town should also have a center for non resource gathering activity (barracks, temple, or library) as well. For this reason I suggest that to advance from a village (1 hex) to a town (3 hexes) you would need a 'town hall' type building and a granary Or alternately 4 irrigated land parcels of grassland, plains, or hills, Or one special agricultural resource like cows, pigs, wheat, corn, tropical fruit, or fish within the city radius. To grow from a town to city (3 to 4 hexes) you will need some form of government structure (a courthouse, castle, or forum comes to mind, alternately a university or cathedral would work. Palace automatically counts as one of these as well.) and fresh water in abundant supply, so fit in the aqueduct and/or fresh water river/lake. From city (4 hex) to metro (7 hex) a hospital And a Provincial capital (new building or small wonder, can not be built within 12 hexes of another Provincial capital). That limits your metros and spreads them out some. Palace counts as one of these two, so the National Capital wouldn't need a provincial building.
Also would like to see the city's radius grow, not just once, and not from cultural expansion either, but from the population size. Culture should affect nation's borders sure, but not a city's needs! A one hex village would only support 7 resource gatherers in the 6 hexes around the village and village itself. That's a radius of 1. A three hex town would support 9 hexes around the village and the town itself for a total of 12 (radius 1). Four hex city-states would support 18 hexes around the city and the 4 in the core for a total of 22 (radius 1.5). Seven hex metropolis' would support 30 hexes around the city and the 7 inside for a total of 37 (radius 2).
Civ 3 Current Size and Support:
Settlement/Town = 9 square support (8 rural, 1 core)
City/Metro = 21 square support (20 rural, 1 core)
Suggested City Size and Support:
Village = 7 hex support (6 rural, 1 core)
Town = 12 hex support (9 rural, 3 core)
City = 22 hex support (18 rural, 4 core)
Metro = 37 hex support (30 rural, 7 core)
Civ 3 Current Growth:
Settlement/Town (9) + 10 Culture =
City/Metro (21)
Growth Suggestion:
Village (7) + Food source (Granary, food resource, or 4 irrigated hexes) + Community Building (barracks, temple, or library) =
Town (12)
Town (12) + Fresh water (lake, river, or Aqueduct) + Government building (Palace, Forbidden Palace, University, Cathedral, Courthouse, Castle/Keep, or Forum) =
City (22)
City (22) + Hospital + Provincial Building (Palace, Forbidden Palace, Statehouse, or Provincial Capitol) =
Metro (37)
Civ 3 Current max Population:
Town (6) + Aqueduct or River/Lake =
City (12)
City (12) + Hospital =
Metro (unlimited except by food)
Projected max Population:
This would be strictly a function of excess food. Any other considerations (water, government) are already factored in by the requirements for the city's size.
Understanding this would require shifts in paradigm from the old system, I'm interested in comments. Please dont just say, "too complicated", be specific
