How you farm cards these days?

curious why you don't want to use ASF? It is so linux friendly.

hl2 = ?

I used to do the same thing, but with vvvvvv instead. Now I use ASF

There's a few of us ;)

I'm guessing a lot of people have multiple accounts if they're selling them for cash. I don't really idle that much myself (just occasionally), and it's purely to level up the Steam account for no reason other than I want to get a higher level... :-|

I just selled a reflectan Yakuza Kiwami card for around 10 euros but most cards cost 1cnt. Totally worth it to farm anyway if you ask me.

If you're not interested in the badges, you can get a bit of credit to put towards a game.
Some of them sell for a lot, and even 6 cents is noticeable if you have 50 cards. That's an indie game or DLC on sale "free", right there.

Same, with 1123 cards.

Idle master is working again.

If you are not scared of a complicated-looking setup, ASF is the way to go.

You can farm multiple accounts with it (although that may not interest you, yet), you don't have to have steam running for it to work and you can also use it to easily activate free games and much more.

Here is the setup guide, in case you are interested:

well, the only way for the cards to drop is to play the games so yes, these apps add playtime

It add playtime but it doest pop up trophies or anything.

Yeah, I farmed cards for a bit, but I stopped on my main account because there were a bunch of games I wanted to get around to playing, and having them show up in "Unplayed" is easier to see them than when they have a few hours on them, haha. Now I still use ASF for my alt account, though a while ago it stopped automatically sending the cards to me and I haven't gone back and fixed it yet, haha.

Also you can "Blacklist" games from it's idling list by adding their IDs to a file, so I've been tempted to do that and start again, since there's quite a few games I probably won't ever play, but I think there's still more that I'd want to play, so I'd have a lot of IDs to add, and I'm not that motivated for those other cards, haha. :P

Most people who do card farming either don't care about their playtime or use other accounts beside their main one, but most of them only do it for the free games they get in giveaways (like the indiegala one since they're random and are mostly good only for their cards) and not with the games they want to play.
In your case, with a profile with a good amount of great games you still haven't played, if you want to farm cards and don't want to "ruin" your account playtime I reccomend to just get a second account where to put keys of games with cards you aren't interested in or you already have.
You can farm the cards there and trade it to your main account later, but beware that you need to get 5$ on that account for it to work but it's easy since you can just send it from your main account (if I'm correct, the restrictions changed a lot of time), and having a second account can always come in handy (more free cards and items during events, can use as "storage" for some of your items, can use the family sharing feature and you can borrow it to friends if someone wants to play something from your library, and probably other stuff).

Im not Volvo.

With this numbers it seems like you got 30 cards every hour for 3 days, but that could only work if the max number of cards was 3 for every game so it seems a little strange since there are many with even 6 cards to drop.
ASF probably told you 14 weeks because it will sometimes switch to farm 1 game at a time in the complex setting, so it would be very slow like that, but it's not specialized in farming cards only but doing other stuff too.
Does IM extended have any problems or may cause some if you idle 30 game simultaneously? I was thinking of starting idling again in my steam library since I wanted to craft some cards during the summer sale but ASF would be too slow.
