You have a lot of F2P games dude.

Free to play games drop game cards based on your in-game purchasing. For every $9 USD spent (approximate) since the start of the Steam Trading Card Beta, you will earn one card drop. This card will drop at some point as you play. If you have made in-game purchases in Dota 2 or Team Fortress 2 prior to the Steam Trading Card Beta, or if you owned Team Fortress 2 prior to the Free to Play update, you will have 4 or 5 additional card drops available.

Nope.

PAYDAY 2 - 60 hrs on record
You're already drop all available cards from this game.

Most games will drop a number of cards equal to about half the number of cards in that game's set of cards. For example, Half-Life 2 has 8 cards in its set, you can receive 4 card drops by playing it. You'll need to collect the other half of the set from other community members. Try the beta group discussions, community market, barter with friends, and trade discussions. You can check how many drops you have remaining on your badges page.
