All the Carpe Fulgur games.

All the games I have yet to play + my favourites.
But honestly I don't know if it's a good thing if they add cards in Braid, I would definitely hunt for the foil badge.

Any Batman game, I really want a background of Batman.
Oh, and Deus Ex and Deus Ex HR too: those are my favourite games.

all the games in my library lol

Shank! 1 or 2 doesn't really matter, but Shank backgrounds would be badass!

Batman Arkham Asylum/City, Max Payne 3, Metro 2033, Dishonored, Assassin's Creed 2/Brotherhood

Don't expect any EA or Ubisoft games to get trading cards any time soon, I would be very surprised if they did.

Hero Academy !

AC series, Bioshock series would have some epic backgrounds !!!

Far all games that I have in my library.

Just Cause, GTA

BATMAN and MK, but since wb never updated mk in pc... it´s really hard to get cards

Final Fantasy 7

Transformers

I would love to see some Ricochet cards!

Planetside 2

Assassin's creed, Bejeweled 3, MW3 / black ops, Eets, Puzzle agent, Sniper: Ghost warrior, SAW, Waking mars, Your doodles are bugged, sonic generations

The purpose of cards is to get badges which increase the steam level, makes no difference which game has given the cards.

Wouldn't magic the gathering be an ideal candidate for cards?

Deathmatch classic. Wonder why?

All games that I own so I can make some $

all the games i have that don't have trading cards yet

Dark Souls.
I got excited when I my eyes quick scanned the list of games and I saw "Dark Fall: Lost Souls". When I read it back properly and saw it wasn't Dark Souls, I had a mini-rage :-)
