Camille said:It doesn't count playtime as "playing the game anymore" alphabet. You genuinely have to earn an achievement for it to count now.
If you have a game with playtime and 0 achievements earned you still count towards the ratio though.
If you have 0 score games and it's affecting your completion then it's just because you registered before that change happened. No new games should show up counting against completions, if you haven't earned any achievements.That's definitely not true. If it stopped counting games I have 0 achievements in, my completion percentage would skyrocket immediately and the reason would be obvious. I only have 275 games with one achievement earned, TSA is counting 446 games. I'd definitely be much closer to my 92-93% I have on Steam. Seriously, only having 45% annoys me to no end because TSA is registering stuff I only idled for cards.
As far as the points others made about DLC, the thing is I only have 3 games with DLC that have achievements with them, and two of those I earned all the DLC achievements for. The two I finished are Tales of Zestiria and Oblivious Garden, the one I haven't is Magicka. But Tales of Zestiria and Magicka seem to not have the DLC achievements even showing as such, Oblivious Garden has shown the DLC achievements fine for months.
I did notice the site seems to be treating achievements added after release as DLC achievements, which is really weird because it's not DLC or even free DLC like Oblivious Garden has. Those are game updates adding more achievements after release.
