Hearthstone — An addictive trading card game w/ surprising amount of depth

Super easy to pick up, very difficult to master -- as the true video games are! The matching algorithm must be a DOOZY because the competition is 90%+ of the time very fair. Absolutely fantastic game. Blizzard really understands the importance of quick games, and visual cues to help the user play quickly and feel smart.

Blizzard took a chance on this and totally knocked it out of the park.
