Update 2

-ECONOMY-

there are a few things to this, population, Tax, Maintenance, industry, agriculture

-Poplation-

First off, you need Population to do anything, this grows once per year, by atleast 0.2% (still to be decided), and your population limits your military, and industry capabilitys, you also have to dedicate 30% to agriculture to feed your peoples (Still Finalizing)

-Tax + maintenance.-

this will work on a simple basis of setting your tax % for the poor, middle, and rich classes, that is added together, then you dedicate your income to certatin sectors, which i will provide a example.

Incomes:
Tax: 5% Poor, 15% Middle, 25% Rich.
Trade Income; 5% - 5% gained from Trade
Commercail Distribution: 5% - 5 Factorys producing Commercial goods
Total: 55%

Deductions: (Max of total Income %)
Building Expendature: 10% - 10 buildings available
Military Expendature: 20% - 20% of population can be mobilised as military personel, and allows 20 ships.
Trade Expendature: 0% - no % dedicated to Trade
R&D: 25% - 25% to dedicate to your Designs or research
Construction: 0% - % dedicated to completion of new Buildings
Debt: 0% - Paying off debt accumilated.

Tallied:
Income 55%
deductions 55%
Tressury: 0%
Debt: 0%

Dept and tressuary allow you to overdraft on incomes, if you have maxed out taxes accross your nation, EG: 100% on poor, middle, and rich classes, that is 300% income, to be used, IF you dont want to over tax, then you can overdraft this allows you to use more money then you have, how ever you have to pay it off other wise you will have negative random events hit your people that will cause problems.

This works into the happiness system, which i will post on in a later update.

-Industry-

Industry requires a number of things, population, resources, and the required buildings.

for a factory to work right it requires Iron, iron is the most valuable resource ingame, and will be the most common and requires a mine to be used, wood will be second to this as it will be required to build your ships early in the game and through out to mid game till a random event allows more heavier ships (explained later)

Your industry part of your post will look liek this:

Iron Mine > Factory > 100x Vehicles per (what ever time is set)

this is the standard for industry, and the only way to produce equipement, i will give a list later on on produceable items per (what ever time is set) this is a set feature.

You will also require a factory to supply shipyards, usualy on a 1 to 1 basis, still to be dicided yet, and will look liek this.

Iron Mine + wood > factory > Shipyard = % of completion let of said ship.

There will be different types of ships mainly the main 7 classes > Island Finder (explorer looks for islands), Patrol, Corvette, Frigate, Destroyer, Cruiser, Capitol Ships, each is a category, and your designs can be based of sub categorys of your choice, eg; battle cruiser, or dreadnaught etc.

other resources will be required to build certain ship classes, Eg: Float stone to help keep capitol ships up due to thier size and weight, ect.

this will be explained further later on.

-Agriculture-

Agriculture is a set 30% of population required, other wise you will be hit with negative random events, that will plague our nations people.
