Zappara, please code into some future version Use a check box option in the menu. Add with it -1 population (applies to settlers/workers) per each unit built in a city and 1-5 turns unit production time depending on the size (warrior is always 1, ICBM is 5). These 3 points will reduce the number of units, makes modern units available quickly and makes magically stronger all tactical aspects of the maps and the gameplay. It will render CivIV to the best ultimate form, quite like the Civ 1 from 1991, the only way I like it too. Especially on giant maps, where you only have to worry about 20 units per empire. The population point will create the right illusion of "men at the battle front". Since nobody has done the three points yet, and they are not worse than other ideas, please find time to add them. Thank you very much for your great contribution to Civ4, we love you for it.
Teemu,
Breaking down what you've asked for into pieces, so that we can hopefully put it to rest. Let's start with the fundamental question of "Can we even do this?"
10 % tax on each single unit out of the empire's current gold income (5 units = 50 %, settlers/workers are free).
This is not possible. Tax and unit maintenance are not related elements. The unit maintenance is determined by one set of numbers in one file, and the civilisation's tax and income are entirely unrelated to it.
Flat out - there is no way to create a logical link between these two elements. It cannot be done in Civ4.
Add with it -1 population (applies to settlers/workers) per each unit built in a city
I think this could be done, but it would mean modifying every single unit to do so. That's a massive, massive undertaking as there are hundreds of them in ROM. It would also mean having to RE-DO this work every time a patch was released. That means a lot of extra work every patch.
So we CAN do this, but it's MASSIVE amounts of work every patch if we do.
1-5 turns unit production time depending on the size (warrior is always 1, ICBM is 5).
How long something takes to build is determined by

. All we can do is tell the game how many hammers and it will always work out how long that takes.
This request is also, sadly not possible.
So, Teemu, 2 of the 3 things you request are simply not possible in the Civ4 game engine. Your request is asking modders to turn Civ4 into a
different game.
Without even touching on the minefield of "Would anyone actually want to play this?", there is no further point looking into your request when two of the three elements cannot be coded.
Instead, what you have been offered is the EXCELLENT higher unit maintenance mod. Which could be tweaked by yourself to make it cost an absolute fortune to have units, and thus give you ROUGHLY what you are asking for.
I suggest you at least try it!
Hopefully this gives you some closure to why your request isn't being picked up.
Cheers,
Sarkyn
