Jennifer Leigh knows games -- she finished 5th at the Poker Royale: Battle of the Ages series. She's known as Jennicide on PokerStars, and finished "in the money" at the World Poker Tour in 2006. Other folks might know her from May's issue of Playboy magazine. In a recent interview with the RPG Vault on IGN, she talked a little about her history with games and World of Warcraft.
WoW's the only MMO she's played recently, but she's been known to play Everquest, Guild Wars, and others. She picked up World of Warcraft during a losing streak of poker, and figured paying Blizzard a monthly fee was would be less painful than continuing her streak. Of course, she runs into the same problem many people do: while she loves her WoW, she has trouble explaining to people who don't get it.
She's surprisingly open about her server information. (For the record, she plays a Night Elf Druid on Proudmoore, and helped found the guild Fate and Fury. Also, she's planning a Blood Elf Warlock.) Between this and the politicians coming out of the closet, I can't wait to see what other interviews crop up.
