Higher LVL of steam is more important or Good Badges?

The only badge I cared about was the Postal 2 one, because I feature it as my favorite game.
Otherwise, I just craft whatever cards I get. Most big games cards are expensive AF and rare, so globally it means I mostly craft badges of poop games. Which is IMO is fine, some even have great-looking badges/emotes, like the :toadPepe: one ^^

A good game library is more important. Lol

I mostly craft badges of games I like. Usually those are AAA or games that has their cards at 10 cents or more :D
Usually sell cheaper ones aka games that I dont care much for. And for that same money buy for the ones I care. Never spent my own money for badges.
To get to 20th level I did craft many cheap badges, where I had to buy 2 or 3 cards for like less then 5 cents. But now after Ive reached it, not really planning to get to 30th lvl that fast :D so know I craft only if Im interested in the background.
Mostly I actually craft them for the sake of backgrounds (I have bought only 1 that I didnt get crafting badge).

No
No
Your choice.
No.

I usually craft the level 1 badge for every game I own (except the cards are selling real good), whereas I try to get to level 5 for my favourite ones.

1 No if it's for leveling up, Yes if the badge, BG, Emoticon is weebs enough for me
2 No, unless anyone can explain to me why do I need so much friend list when most of my games are single player
3 Since I've seen You kinda enjoy playing with Humanoid cats, You might want to check my badge list. Also most weebs game badge are good looking, well, for weebs only tho
4 Nay, and I'd rather they let us choose x level version badge even if we already reach lvl 5, since some level 5 badge not better than earlier level

f*ck grammar

By farming on 5 accounts (1 50+ lvl, the rest below 10), I can say that the difference is minor. IMO it is not worth it to level up. The only reason I personally did it, was to get the showcases.

1- I used to. I had a whole system worked out where my higher played games got higher level badges. 10+ hours equals Level 2 badge, 25, 50, 100, 250 is foil. That way, the games that I put effort into got their badge recognition.
Then I realized that would cost a ton compared to getting cheap badges.
2- I haven't before, but I am this Winter Sale. I got like, 5 keys and traded it for a bunch of card sets. I should level up past 50 this sale.
3- Search for badges by name for things you're interested in. For example, I got the badges related to penguins.
4- No, just make sure your trash ones aren't one of your most recent 4 and it won't show on your main profile. Nobody really looks into your specific badges anyways so it's just a personal thing.

If a game a really like has a badge, I'll get that badge. I mostly use money I get from trading cards to buy other trading cards.

Working to get higher booster pack drops is no joke - a booster pack dropped a foil card I sold for twelve dollars and fifty cents. I bought a whole-ass game with that money.

I try not to think about it too much, though. I'd like to find more heart-shaped or star-shaped badges, though, but I want it to be from games I care about.
