I spent Saturday at Gen Con 2009, and while I didn't play any World of Warcraft, the game was still out in droves. Biggest of all of the events and displays about WoW was Upper Deck's massive TCG/minis area -- the place was crowded with players throwing down in both the card and figurine games. Back on the exhibition floor, Upper Deck was also demoing both games, as well as running their usual Darkmoon Faire promotion.
And they weren't the only company showing off World of Warcraft-licensed products -- Fantasy Flight games was showing off both World of Warcraft: The Board Game, and World of Warcraft: The Adventure Game at their booth and back in their gaming room. Gen Con is a gigantic convention, so as big as World of Warcraft is, it was only a drop in the flood of gaming going on this weekend (and Blizzard wasn't there officially at all, likely getting ready for BlizzCon next week instead). But wherever there are dice rolls and card games, you'll probably find some sign of Azeroth.
