Blizzard has announced their latest game - you know the one they teased last week - revealing Hearthstone: Heroes of WarCraft. Another departure from the direction that the WarCraft universe has been heading in, Hearthstone is a development from a much smaller team within Blizzard, who were looking to create something to serve as an entry point into the WarCraft Lore. What they came up with is a competitive card game, which finds players building a deck and challenging other players for prestige and new cards. Reactions are mixed, but personally I'm liking the concept - to the point where I've signed up for the beta. Have a look at the trailer above, and the video for a bit more detail about the game, and let us know what you think in the comments.
