sorry for the delay on this, working long hours leaves me little time, at the moment i may have time this week end to put into this.

for the tax and maintenance system im def set on abolishing the every person pays $2 tax, every soldier costs this much and etc etc, cause thats a headache i no longer want to deal with.

the new system will be based liek this somewhat though how i'll set it still pends.

Tax: 30% (Poor: 5%, Middle:10%, Rich 15%)
Trade: 10%
Commerce: 30%
Total 70% of total economy income.

Max expenditure: 70%
Military Spending: 30% - >still working this out :/
Industry: 20% - 20 Factory's for production
R&D: 15% - 15% to spend on Designs, etc
Construction: 5% - 5% for to spend on buildings construction

it will look something like this, a tone lot easier then a whole list of math sums, and makes more sense in the end really, there will be a debt system as well, if you want to do special massive projects, which would be like 20% over expenditure that would build up to an unlimited number or a capped still pending of like 500%, and the way to pay it off would be lowering the expense spending to gain like 5% profit or something.

It also allows you to tax your people accordingly, so if you tax your people 100% across the board you will have 300% income.

BUT this also ties into the Happiness system i will put in place, basically be on par, 50% total tax = -50% on the happiness of your nation, and so you have to gain resources or etc to increase that happiness.
