Blizzard is looking to do a mix of Naxxramas and card expansions
Hearthstone is still chugging, and I had a blast with its Curse of Naxxramas expansion. It added a decent amount of cards to the game (30), and some single player content that kept me busy for quite a while.
The next expansion though won’t be taking the same direction though, as it will solely consist of cards — lots of cards. Speaking to Polygon, production director Jason Chayes noted that there will be “more than 100 cards” in the next expansion, and that they’ll fit a central theme.
Although the Naxx concept worked well, Blizzard has a long-term plan for the game that involves both card expansions and adventure content. It’ll be interesting to see how a “just cards” expansion fares, and if Blizzard can keep Hearthstone balanced.
