I see that there are practically no achievement support on newer games, in older times when new game was added achievements were added same time or maybe in a day or two,
now as I mentioned no new game that I encountered and played has it. Is there any particular reason for this? at least information would be somewhat helpful, thanks.
It's due to a change made on Steam a while back. While we for some reason can grab what achievements there are, it is not linking them correctly. It typically comes up that all the achievements are secret/hidden, even though they're not supposed to be. We are aware of this though, but just have not had the time to make the changes. If and when it does get fixed, it should work retroactively and grab everything.
