Mojang's collectible card game / board game crossover - Scrolls - is set to launch next week, and will cost $4.99 (there's no UK/Euro price as yet).
The Minecraft creators have also revealed that they'll be restricting the amount players can spend in the game on additional units, so as to avoid unbalancing it in the future.
"We restrict how much you can spend to retain game balance," Mojang explained. "This sounds unlikely, but you really don't have to spend more than the cost of Scrolls ($4.99) to progress. All items are available for a reasonable amount of gold."
The game's coming out of beta on December 11. The base will cost $4.99, and a free trial version of the game will also be available to download.
