But why does everything have to be so balanced? In real life, people are not balanced, countries are not balanced and historical civs were not balanced either. Why this taboo to have some civs being underdogs and other being easier, just like it would be to choose Portugal in HoI2 or in next game play USA. They are not equal and shouldn´t be equal. And that what makes it fun and interesting!!
Except that in Civ you are generally starting from the beginning in which all things are more or less equal. In HOI you are not. You start at a set point (1936) where some nations are indeed stronger than others.
That's the whole point of Civ. You start as equals and try and rise above the others. Unless you choose a high difficulty level where you start off a little less than equal to challenge yourself or vice versa. All Civs are more or less equal.
