I really dig this site. Whether you're buying a game, or finding a news article about an upcoming game, it's a great source for Adventure gaming.

Ah, adventuregamers.com. I don't visit it often, but I do once in a while. I tend to get almost all of my video game news from Joystiq, but they don't specialize in adventure games. Nor do many other websites, for that matter XD
