The next big thing in massively multiplayer online games might very well be the decidedly old school world of card games. Online trading card games to be specific.

Since its August launch inside Everquest and Everquest II more than 4,500 matches of the Everquest-themed online trading card game Legends of Norrath have been played.

SOE president John Smedley told me in a recent interview that more than 30 percent of the MMOs' players are currently playing the trading card game and that they've sold more than 5,000 virtual boxes of booster packs for about $100 a pop.
