UgLyPuNk writes "Blizzard has revealed its 'something new' at PAX East 2013: Hearthstone: Heroes of Warcraft — a 'charming collectible strategy game set in the Warcraft universe.'" Blizzard says this game is a departure from their normal development process: it was made with a team of just 15, will release this year, and it's free-to-play. Hearthstone is built for Mac OS, Windows, and iPads. There's a deck builder, a match-finder, and AI for those who don't want to play against other people. While it's free to play, and players will earn new packs of cards by playing, there will also be an option to purchase new packs.
