Can I reset achievements without affecting Steam achievements?

[Clair]

I want to try a "100% Achievements Speedrun," but I'm sentimental to my achievements on Steam (the first ones I got for Factorio date all the way back to 2019, it's kinda nostalgic.)

If I delete achievements in the settings menu, will it also delete Steam's achievements, or just the ones local to my computer?


Somewhat related, but I do wish game-local achievements were a thing, since triggering them is always a nice dopamine dump, even if I'd done so once before.

as far as I'm aware, steam achievements =/= in-game achievements during modded runs

Deleting your factorio achievements will not persist to steam achievements that you already have.
I am unsure that it may or may not reset in-progress counters such as "Craft 20M Electronic Circuits"

Your best bet for doing a 100% achievements speedrun is to add a QoL mod, or any mod in general, as I believe that saves with the world's save file.

I think I read somewhere that deleting achievements in the settings menu will propagate the change to steam. (Assuming you are playing the steam version).

However there is another way to achieve what you want. Download the .zip version. That is a fully independent and portable version, and will start with no achievements unlocked, allowing to do a 100% achievements speedrun without affecting your steam achievements.
