Have you already found a booster pack?

Got one for Monaco. Haven't gotten another one ever since.

yes for faerie solitaire, but sold it.

Found it. Unpacked it. Regret it.

YES

found it. sold it. good :)

I got one for fairie solitaire.
The only game my gf has collected all the drops from is They Bleed Pixels and of course she got a booster pack (lucky), when she opened it, no foil and she got 3 duplicates (not so lucky) lol. and she can't trade yet cus she's a newbie

Yus, Trine 2 one.

ciaooo, just got the trine2 one, no foil inside:o

I got 1 Portal 2 booster pack but no foils

Yup, Faerie Solitaire's one, but no foils :<

L4D2 but only useless shit

not yet :(

No, because steam is cheating me. All I want is to craft badges :(

Yes, 1 booster pack. No, no foils. After clearing at least 10 games worth of cards.

Nope.

Got one for Super Meat Boy. Sold it and with a bit of extra I bought Magicka for 2.49.

BTW booster packs don't drop. They are distributed.

Got one, sold one. Didn't take the risk to open it as it seems the chance of getting a foil card is 1:100. IMO it's better to claim €1,5 than a 99% chance of getting 1€ and 1% of getting 3-4.

My brother got one, but no foil

I got one on the first day of the update.

I have yet to find any booster packs,although i found one foil (Plea)

I edit my post cause i received one on sunday

Just got one for Serious Sam 3 BFE. No foils

Do you have to be playing the game to get one or is it completely random?

no

Had all my possible card drops for ages, and play CSGO (and now also FTL) loads but I'm yet to have a booster drop or have gotten any foils.
