How can I reset the game so that all my achievements are deleted?

The only legal way to do that is creating a new Steam account and family share it with the one you purchased AoE 2 on.

There *might* be a command line argument. (from my research a while back. I remember finding one.) However, since I never wanted to test it myself, I never tried it. Most likely, it only works in debug mode anyway...

and no, I rather not say what it is sorry. (I'd have to look again and find it anyway...)

I want to cancel the achievements only in the game itself

[FloosWorld]

As it resetting campaign progress?

Yes

Well... After thinking about it, there is no way to (intentionally force it on someone that I am aware of via modding. So, it should be fine right? although... you could be tricked into it... although, that is kind of on you at that point...) be used for evil purposes... (I still don't even know if it will even work anyway...) Well... okay, lets try this...

You are aware, if you try either of these command arguments below, you are using it at your own risk. It may/may not work. I do not know. Debug Mode may be required for it to work. Which is it's own command. Which (assumption.) I don't think works without the games source code. I am not responsible for any issues that arises. If anything. Most likely, nothing will happen. Just remove it afterwords if so.

edit: Add this Launch Option via Steam -> AoE2DE (Game) -> Properties -> General -> Launch Options (Minus the '' quotes.) and launch the game.

'RESETACHIEVEMENTS' - Resets steam achievements, stats, and Art of War medals.

edit: there is also 'RESET_STEAM_STATS' - Reset all steam stats and achievements.
