Europa Universalis V: Enable Achievements Unconditionally

Steam Community guide by UFOdestiny.

Introduction

The debate over whether unmodified ironman mode should be required to unlock achievements has been going on for years. While games like Crusader Kings III and Stellaris have adopted a more player-friendly approach, Europa Universalis V has unfortunately taken a step back.
This patcher allows you to:

• Enable all achievements in non-ironman mode.
• Enable all game rules in non-ironman mode.ModeModSettingConsoleSave & LoadAchievementsNon-Ironman✅ Any✅ Any✅ Yes✅ Yes✅ Yes
