free games have most of the time the signum „steam is learning…“ or „ profile feature limited“ on the store page. that means they dont show up in some profile values, for example achievements value, 100% on the profile (but when you click on the value, it opens a new side with in it), games owned value…you can not achievements show up in the showcase from this games and so on.

Games that don't count for the profile count and gamers badge:
- Free to play games;
- Games with "Profile features limited" on the store page;
- Games with "Steam is learning about this game" on the store page;
- Games banned by Valve.
