Total Realism

Description
From Total Realism Team here comes one of the greatest mods available.

Not to forget anything I'll have to quote the authors :)

[quote]One of the greatest Mods ever has finally been released. Including more than 50 new units, new Mod Components, new ideas developed from scratch, rewritten and extended most of other known mod Components according to the suggestions of our fans and our analysis of a more balanced game play.

This Mod takes Civ4 a step further. Our philosophy for this mod is easy and straight forward: We empathize on three stages:
1) Game Balance, Unit Balance, tactical balance between all available Civs
2) Realism: Archers shall not destroy Tanks. More realistic warfare and strategically depth by using the advantages of your units to counter the enemy.
3) Fun: This is why we are here, right?

We have extensively modified the Game play according to realistic Warfare, Politics, AI decisions, Trade, exclusive religion mod, realistic raze city, unit-counter-strategies and much more.[/quote]
