You can run as many games as you want.

After the 2 hour timer cards will drop but if you have more than one game running card drop increase making it take longer to drop a card.

Also it's just a suggestion and there is no evidence it can happen but I suggest not running multiple games with IM and VAC enabled games. While no one has been banned to my knowledge for running IM and playing a VAC enabled game why take that risk on your account for cards.

I believe the issuse is with Idle Master.

Lately it is reporting that you have more cards to idle for than you really have. For me it currently says I have 39 games with 472 cards left.

To see if you have any cards to idle for go to your badge page and search for "PLAY " (minus the quotes and with the space after y) This will highlight any games that still have cards left to drop.

All games require 2 hours of playtime on it before it will start to drop cards.

This was a change made recently by Valve because of the refund policy.

Also lately I have noticed that Idle Master is not reporting hte correct amount of card drops left. For whatever reason it is saying you have a lot more cards to idle for than you really have.

Best place to see what games are eligable for card drops is your badge page. There you can see what games have free carddrops left as well as what games have two hours on them already.

Good for you. No one ever said you WILL get banned but it is advised not to.

While I can't prove you are doing this I also can not prove you are not doing this. The internet is full of trolls and losers who will do anything just to be an asshole and get people to do stupid stuff. And the internet is also full of idiots to feed those trolls.

My account is not worth the risk.

jshackles is in the process of incorporating IM:H into IM.

I'm sure once he does that everything will work great.

Until then just run IM:H to get any new games you have added to your account to the 2 hour mark before you run IM.

It's a pain but it's still a lot better than having to manualy download these games for cards :)

My suggestion is to NEVER us IM while playing ANY game.

If you are using IM to idle for cards and run another game it will cause the drop rate to slow down making it take longer for cards to drop.

If the game you play while running IM is a VAC game then you run the possibility of a VAC ban. While no one to my knowledge has been banned for this is it really worth the risk to your account for a silly virtual card?

Try reading that again....

all of your available Steam Trading Cards - even from games you don't have installed!

You still have to OWN them .. you just do not have to install them. IM simplifies the retreival of cards by "tricking" steam into thinking you are actually running the games exe. Saving you the time and trouble of actually having to download and install the game.

You can not get cards from games you do not own.

Where did you read that it gives you cards for games that you DO NOT own.... that doesnt even make sense.

Yeah I have 37 games and 417 cards .. That's an average of 11 cards per game so it's definitely wrong.

There are issues with the badge page. Been that way for a bit now.
Things like I can still see the summer badge and the cards. It used to be gone.
I can no longer look at my Booster Pack eligability it just loads indefintally.

So Valve must have done something to the page to cause Idle Master, as well as the badge page, to break.

cards do not drop every 15 mins.... The timer is there to let you know when Idle Master will check your badge page to see if any new cards dropped for the game it is idling. If all cards for a game have dropped Idle Master will move on to the next game.

First before any cards will drop there needs to be 2 hours of playtime (idle time) on the game. Once that has been reached the game will start dropping cards. The 2 hour time limit is because of the new Valve refund policy.

After cards start dropping it can take 2-3 hours on average for any remaining cards to drop.
