In 2013, Valve introduced Steam Trading Cards. The premise is simple. You play games and earn virtual trading cards. It might take selling 100s of cards, but you'll eventually stack up enough credits for a cheap game.
most cards give you a cent or two. Selling enough cards to buy a cheap game means you've already spent a fortune in games to play and earn said cards.
Eh. It depends. If you're a regular PC gamer, you likely use Steam a lot. I've sold many cards ranging from a few dollars to 10 or 15. Hell, I put a card on there for almost $100, and some joker actually bought it. But yeah, it's not a realistic way for people to make any real cash in general.
