Hearthstone’s key to success: Blizzard lets team make its ‘dream card game’ (interview)

Hearthstone is the latest success story for a studio that already had its share of them, but something about the free-to-play digital card game for PC and iPad (with iPhone and Android releases on the way) seems special.

Usually, Blizzard works on large, expensive, and epic games like World of Warcraft and Diablo III. But Hearthstone is making a huge impact of its own thanks to charm and engaging gameplay. It released its newest expansion, Goblins vs. Gnomes, earlier this month. It added 143 new cards, vastly changing the status quo.
