The country of us: Subject Expendby Qsepe11本Mod旨在将自身的土地委托给AI，建立富有情怀或是具备游戏性、功能性的独特附庸。在MOD内容中，他们通过“附庸升级”、“释放特色附庸”为核心。目前，本Mod为游戏添加了60种新的附庸类型，大致14(帝国总督线)+20(殖民线)+4(蒙古汗国线)+11(都督线)+2(都司线)=51种新的可释放附庸。然而本Mod仍未完成，未来将继续添加新内容。由于Mod为作者个人制作，更新速度较慢。既然是“委托给AI”，那么在理论上这些土地仍然由我们所有，且AI国家不会使用该MOD。因而本文中的大部分附庸不占用外交关系，且独立倾向都显著低于原版，一个附庸大致可以在拥有四百发展度的情形下仍然向您忠心耿耿...6.8k downloadsupdated 4 mo ago
