How to add free to play games in steam account.

Have you played it?

keep the game running until it shows up in your "recently played games" list, then sync your SG account again.

I think you need to play them for SG to see you have it.

Try to play it for 10-15 minutes and sync again.

Play it; it's fun.

Install it, play or start it at least once, wait a few minutes and forcesync your library here

Pathetic. Trying to win a DLC for a free game you not even playing.

for an odd reason, you need to install the F2P games sometimes for them to sync properly.
