比如我要改 不列颠的特性为 第一、二、三个       
 
britain
        {
                specialty1 = 0        //better_colony_morale
                specialty2 = 1        //better_effect_from_church
                specialty3 = 2  //better_supply_of_colonists
        }
注意 // 后面的只是英文说明，不改也可以，在游戏里没有任何影响和也不会显示该段话
 
这样修改后，进游戏，不列颠实际已经是0，1，2的3个特性了，而不是3，8，14的三个特性
但在开始选择国家和外交界面里，仍然显示是3，8，14的特性，下面还有一个地方修改
