Today we're making Steam Trading Cards available to everyone. Steam Trading Cards are virtual cards you can earn just by playing some of your favorite games, like Team Fortress 2, FTL, GRID 2, Monaco, Trine 2, Super Meat Boy, Counter-Strike: Global Offensive, and more. In total there are over 30 games with Steam Trading Cards, with more being added every week. Collecting cards lets you craft new badges for your Steam Profile and earn rewards like emoticons, profile backgrounds, and coupons.
We've also updated everyone's Steam Community profile with a new look. The new profile has a more concentrated focus on what you play and how you participate on Steam. There are new customization options as well, like the new profile Showcases that let you choose what you want to show off: favorite games, items up for trade, workshop mods, hard-earned achievements, and more.
Additionally, you'll see a new "Steam Level" on your profile, and when hovering over a player's avatar. Every badge on Steam now grants XP, which contributes to your Steam Level. If you've been a Steam member for more than a year and have at least one game on your account, then you've already got two badges. You can earn more by participating in events and sales, collecting trading cards, trying out all the Steam Community features, and more.
