Despite first being released on PCs, Hearthstone is, I believe, the inevitable result of tablet gaming. I’ve long felt that tablets are an ideal medium for board and card games – I’m also hopelessly addicted to Ascension, for example – and Blizzard embraced that by creating an incredibly-polished collectible card game that anyone can pick up and play. The twist is that many of the rules would be incredibly complicated (if not impossible) to implement in a physical game, which I think is where tablet card games truly shine. I can’t even imagine playing the physical version of the aforementioned Ascension, since there’s just so much to keep track of.
I would seriously recommend it to anyone who owns a tablet (especially now that it’s on Android), but I take no responsibility if you end up hopelessly addicted. You have be warned.
(But seriously, it’s super-fun).
