Countries unions like NATO,E.U, etc will be nice with voting and vetos for wars,embargos and for economy and military help.
And what about for 2 indivitual lines of productions in a city.One for buildings and the other one for units?

This has been discussed thoroughly in other threads ;)

That is an interesting idea. :)

Perhaps you'd have a slider bar to control what percentage in the city goes to each.

Well i m new and i didnt read yet all of the ideas but thanx
Another thing that was good i think is a consept of trade of Gold and Research point.
Example
If you made an agreement with another civ for let say 20 turns for trade or research point.You can both benefit of extra gold and research point in every turn.
Its like the old strategy game Master of Orion 2.
Its not a big idiea and probably will already been postet but i think is a very good idiea to get everybodies opinion for these great game so it can become the greatest.
I just one to asked for the "Grand us a loan?"have ever been used by somebody?

Welcome to CFC ErihVonManstein!

Did you get this *idea* from GalCiv? Its got a great money-system. There are four things that are different from Civ3:
% people are taxed
% goes into: research, military, and buildings
% goes to 1% instead of 10%
% tax effects happiness
I hope they include those in Civ4(IV)
