Are Steam/Valve aware of the achievement glitch on certain (all?) games?
That if you are more than one steam-user on a computer and have the same game, the achievement unlocks for all owners of the game.
For example, my daughter just got two achievements in Monster Loves You just by starting the game. War, All Humans Dead & War, Endless Fighting
I think it has more to do with the way how some developers implement the achievements. I once helped someone to get his Binding of Isaac achievements because that game has a bug where it doesn't unlock them. The save file for those is somewhere in the AppData folder in your user path on windows. So I replaced it with his and I got all achievements he earned on startup. Could be the same here with how the game accesses the same file. I'm no expert though^^
