"the higher it's True value should be."

Should be "its".

But why a square root? To prevent ultra rare achievements from becoming too valuable?

Some of the ratios get crazy without itAlright, thanks for the answer. I've got another question... how do you guys count gamers? Do gamers who play the game but haven't earned any achievement count? And do gamers that own the game but never even played it for a single minute count too? I guess it would work best for the algorithm to only count those who have earned at least one achievement, what's your opinion on that?

I guess it would work best for the algorithm to only count those who have earned at least one achievement, what's your opinion on that?Speaking from what I saw on my own tag, gamers who played the game are counted regardless of achievements earned. With TT and TA it was only after your first trophy/achievement but then again actual played games were harder to count on those (and you could delete the empty trophy/achievement lists from your history).

I think this is the best option. Even if you haven't obtained an achievement, you did actually play the game. This helps a lot with one-achievement games. Gamers who have the game but not played it should indeed not be counted.

The only issue I see is games that initially had no achievements, but got them added in an update years after release. "NightSky" is an example of that. All of it's achievements are pretty "rare" on Steam, while they actually aren't that hard. It's just that a lot of players played the game before it had achievements. If only we could start counting the players from the moment achievements are implemented...

Another example of this is "VVVVVV". However, that game got updated with pretty hard achievements, so the rarity of the achievements seems accurate anyway.

In cases like this I guess the achievements should be put in a "title update" DLC pack, like TT and TA do with trophies/achievements added after a title update. Only weird thing would be that it's achievements in DLC when the original game has zero achievements but I guess this is just something specific to Steam that we should get accustomed to.

This will be buried, but I'm pretty curious about the math.

Clearly you need an increasing function of the important value:
Total_players/Players_that_have_the_achievement

but why exactly the square root?
I'm curious about the idea behind it.
I mean, why not a 3rd root? Or a logarithm?

(Id guess square root since most people know what that means)
