Sorry for spamming your thread but I assumed it might be good to put the same issue on one place, as I was about to write a discussion about that.

A person I gave a bunch of games to idle is having the same problem.
It is taking him 3-4 times more to idle a game, than the average time.
For example it took him 15 hours to idle Axiom Verge.
It took him 8.4 hours to idle 16bit trader, compared to my time, which is 2.6 hours.

I am not sure what might be causing that and why is taking so much time to idle a single game.

i'd recommend running games simultaneously, if there was a set time for card drops people would play each game for that time. The drops are random. This is no issue with idle master but instead so to speak with steam. Without the use of idle master. (Playing a game to it's full potential.) There have been times where I've completed a game from start to end twice and not gotten all the drops. Ohh and brake P.S. were these games obtained by you for free or did you pay for them & gift them? If obtained for free can you add me and msg what games, or what method was used? Thanks.
