Fitgirl is a repacker, not a cracker so this really depends what kind of a release is it, so you’d have to test by yourself.
It should work when it comes to launching the game, I’ve done it before in the past. But in theory, it’s unlikely to work with achievements given how cracks tend to overwrite the steam api dll files and hooks, likely disabling achievements in the process as part of the crack.
Something you could try is to copy the steam dll files like steam_api64.dll from the original copy on steam to the cracked one and see if that does the trick.
I mean, even this kind of argument doesn’t really work in reality. We already live in “hell on earth”, and via electorialism usually two choices are given: the progressive “nothing ever happens” option (so your socdems, democrats, you’ll be lucky to get a good policy or two but no real change to the status quo) or “literally hitler” option, maybe some parties that stand in the middle of the spectrum if the country is “advanced” enough.
In other words, via electorialism you can either preserve the hell on earth or make it worse, and the process of voting legitimizes this status quo as it’s what “people have decided” rather than who the ruling class cast as candidates, who had the most money and media influence for campaigning.
It’s important to see electorialism for what it truly is.
