I started the Hearthstone closed beta yesterday. I went into this with mixed expectations, mostly trending toward the skeptical side. As I should have expected, this game is excellent. Foolish of me to think that Blizzard might come out with a sub-par product. The few people I've chatted with are already in love with the game.
My interest in CCGs is limited at best, so I probably won't be playing this long term. But I can see those that do like CCGs playing this for a long time, especially if Blizzard is diligent with expansion sets. I threw the $20 I made from the D3 RMAH into the 15 pack option. Store worked perfectly with options for both Battlenet balance or straight credit card purchases.
Anyone else involved with Hearthstone yet?
