When Minecraft made a squillion dollars, rather than plough into a sequel, developers Mojang Specifications realised they could fund making whatever games they jolly well pleased. Scrolls [official site] was their first whim, a battling collectible card game. And, since Microsoft bought Mojang, it might be one of their last too.
The most recent Scrolls content update ‘Echoes’ will be its very last, Mojang have announced, and it sounds like the servers will shut down eventually, though not for a while: they’ll keep going until July 1st, 2016, at the very least. The game only officially launched out of beta in December 2014.
