If all you want is Exp, just purchase the cards off the Market. Both of these sites have sortable tables to find which game has the cheapest sets.
http://steam.tools/cards/
http://www.steamcardexchange.net/index.php?badgeprices

Currently CS:GO is the cheapest, 0.25$US for the full set.

If you want to purchase the game here's a site that will show what games are on sale
https://steamdb.info/sales/

No game is worth purchasing at full price if you're looking for Exp.

help, the program says iddling complete, I have to do to make it work ?

Double check your Badges page to see if you have drops remaining. Looks like all your STC enabled games have sufficient playtime to have received all of your free cards.

Non-F2P games only give you half (rounded up) of the number of total cards in the set. Duplicates will count against that number. Trading/Selling/Using those cards will not give you additional drops.
F2P games require that you spend 9$US for each.

Double check your Badges page to see how many drops you have left. All the STC enabled games you own have enough playtime to have received all the allotted free cards.

Not every game has cards. Of your 14 games it looks like only 4 of them are STC enabled and one of the (TF2) is F2P which means you need to spend 9$US for each drop you want.

You only get cards if Steam thinks you're playing that game. Having Idle Master falsely report playing a non-Steam game would accomplish nothing.

Double check your Badges page to see if you have drops remaining. Your games have more than enough playtime to have earned your alloted free cards.

Playing a game only gives half (rounded up) of the total number of cards in the set. Duplicates will count against this number. There is no known way to reset the number of free cards you get. Selling/Trading away your free cards most definitely does not earn you additional free cards.

Double check your Badges page to make sure you have remaining drops. You have more than enough time in your non-F2P games to have received your alloted free cards. Trading/Selliing those cards will not allow you to get more free cards from those games.

Neither of the games in that picture are displaying playtime on your Games page. Are you running Idle Master while in Offline mode? Are the games being forcibly closed moments after it starts?

There's been a couple of reports about the games crashing moments after Idle Master starts, but I don't recall any solution.

Could you be more specific?
Is Idle Master not starting? Not connecting? Setting your computer on fire? Are you getting the "Idle Complete" message?

The 2 hours before normal drops is fairly recent (~2 months)
The reduction in drop rate for running multiple games has been around since Beta.

Same here

Same point. You own 1 game and have more than enough time to have received all of your alloted free cards.
