eu4的商人数量是理念和各种buff以及基础设定决定的
存档里面没有专门的一个数据，
但是你可以新做一个modifier
然后进游戏获得这个modifier
最简单的方法如下
打开游戏安装文件夹【或者某个mod文件夹】\common\triggered_modifiers
新建一个txt文件，命名英文即可
粘贴以下内容
player={
potential={
ai=no
}
trigger={
ai=no
}
merchants=x
}
x=你需要的商人数量
这样所有符合ai=no的**会得到这个buff
即使你蹿档玩别的**这个buff也会带过去
原来的**也会失去这个buff
同理、也可以在最后一个反括号之前加各种其他的数据、
比如其他专员数量、科研速度之类
国外官网找了个modifier的大全、希望对你有所帮助
【一条一条翻译太多啦、好在都是本意、可以直接谷歌翻译解决】
