Played the mobile version before it came on steam. Pretty much a better version of Hearthstone. Less RNG and a more interesting mechanics and card abilities. Has anime tiddies all over the place if you're into that, but otherwise the card art is pretty nice. Devs give out free card packs all the time and there's loads of ways to earn currency to buy them with ingame currency and the game actually has a campaign that you don't have to pay for. They also give you 30 free packs to start out with.
If you liked hearthstone, but you hated how the meta turned out and the ♥♥♥♥ balancing along with the RNG fiesta, then this is a great alternative.

Fun Team-based shooter from the Guys who made Wolfenstein: Enemy Territory and Brink. Game really rewards teamwork and punishes lonewolfing which is a rarity nowadays (K/D doesn't matter unless you are a damn child). F2P system is similar to LoL and isn't as offensive as most other F2P games.

I will find you and cut you if you are an assault and you don't give me ammo.

pretty good
