Did you try any of these game?
I have tried the first three and they did not give any PC.
I know they have PC logo within the game but no PC after playing them.
The same also with Guitar : Solo Lite
It has the PC logo but no points. It is a nice guitar simulator.
Also I think that PC works on a 24 hour cycle and not calendar days.
So if you played a game yesterday but 22 hour before you will not get points.
Did any of you have the same experience?
