Scrolls is the second game by Mojang. It is an online hybrid of a collectible card game and a simple but deep turn-based strategy game (son nothing at all like Minecraft). You can get alpha now for 10 dollars (or was it 15, page won't load for me atm).
Besides NP2, it is the only thing I play at the moment, being limited to my netbook. Beyond paying for the game there is an in-game store, but you cannot buy scroll packs for real money, you have to earn gold by playing to get it. You can only get the starter decks and cosmetic items for real money. Earning money to buy scrolls is fairly easy.
Check it out. Maybe we can play sometime, once they add a friends list (which is on their to-do list).
