To quickly explain it all.

The 2 hour limit will apperantly change after that the Steam Refund time has suspended so that you then get drops as before that was added.
You CAN get drops by doing multible games at once BUT it will be slower. The rate drops the more games you run at once to the point where doing them 1 by 1 will probebly be faster.

Connect to your steam account like it says?..

Exactly what was just stated above. "steam-idle.exe (GAME ID)"

It is completely random, so no there isn't. The only tips I can give it do not run multible games at once that will drop the rate of getting cards. Also if you start to Idle other games it will first make sure you have 2 hours played since you need 2 hours played to get cards (most of the time it happens you don't).

Thanks :D

You don't get it it seems... I know that... I want to know how to just run the games to increase my time. Since you can run 30 games at once to get their time up to get the 2 hours to then get drops. There should be a command to run multible games at once to increase multible timers.

I know you can run a game to increase time played by typing "steam-idle.exe ID" in CMD, but I have 2 questions.
How do you find the ID's?
Can you run multible games to increase their time? Since you can run 30 games at once to get 2 hours on them for the drops?
