I have the “Edward Kelly” achievement in Kingdom Come Deliverance due to brewing 15 types of potions. Only 3.3% of players have it, which is pretty high compared to most of the ones posted here, but it’s still a little interesting. Brewing potions in the game is a bit boring, and you can easily buy all the ones you need, so it’s understandable why few people would get it. I just kinda decided one day I wanted to get to auto-brew level of skill and that meant lots of potion. Might as well make as many different kinds as I can, and auto-brew requires you’ve done it once already anyway.
Brewing potions is so fun in this game. But i don’t have the achievement because there are some that i never used therefore never brewed
How do you check again how many copies a game sold?
Because I have some 1% achievements in games that sold millions, but I’d argue my “20% of players” achievement in a 200 reviews game is rarer.
Not quite official figures, but SteamHunter can show rarest achis in terms of absolute user numbers, and yea most of mine are from very obscure games, or games where the unlock was bugged for most players.
this is a free game, but I don’t think there are a lot of people who have played it (delivery & beyond).

otherwise it’d be these for tabletop simulator

This thread is a self doxxing minefield
ah fuck, now everyone will know that I’m actually a trash girlfriend alt account
Are achievements public?
Depends on your steam profile settings
Being online is a self-doxxing paradise
Not counting rare ones that are from brand new DLC, this is my rarest (Stellaris).

With another rare from a different space 4x game (Endless Space 2):

I have 113 hours in Noita and I still suck.
Close to my rarest, but very fun and surprisingly strong! From Victoria 3

My sibling, why would you ever play witch it on an official server?
I have all the achievements for Final Fantasy 1
Not at all an achievement hunter, and Steam is not my default gaming platform…
But I checked my rarest achivements and I’ve got a 1.4%. Which does not sound much, except it’s in fucking Skyrim, and absolutely trivial to get.
OK, there’s the catch : it’s because this is Skyrim VR. It’s the achievement you get just for mining ore and chopping wood.
Looks like there are some relatively easy .3/.4% to get there if you’ve got a VR headset and some dedication. And manege to keep the game working long enough to get those. That might be the hardest part, because … Bethesda.
Factorio Express Delivery was quite an effort and a lot of fun.

I also have some fun Europa Universalis 4 achievements that were at 0.1% when I got them, but it seems that I need to up my game there :P



Not as rare as some others, but takes a little while to achieve:

Still working on Super Go Outside
Hahaha I have that one, and got it fair and square.
Ohh, right. Thanks for reminding me that I can get this one now.
I also got that one fairly.
Two of my rarest: Dune Awakening

Dispatch

My overall showcase

And probably my proudest accomplishment

From American Truck Sim
Cornfusion Drive to the center of the Evergreen cornfield maze (requires Illinois DLC)
It says .1% of players
new one from an update in March, so will probably drift down the list:

long-term rarest:

all my remaining rarest ones are from Civ 5, I guess most players don’t have the DLC
