Can Idle Master be used to pad my playtime of a particular game?
The steam-idle.exe application that's included with Idle Master can be given a command line argument of the appid of the game you'd like to idle. For example, if you'd like to idle Team Fortress 2 for playtime, you can simply run "steam-idle.exe 440" from a command prompt. There is no user interface for this, it must be done through the command line.

I typed steam-idle.exe 730 in command prompt and I get: 'steam-idle.exe' is not recognized as an internal or external command, operable program or batch file/

kill it with fire
