"In just its first month of testing, an estimated 50,000 people signed up to use Xfire, which functions like an instant-messaging service. Gamers can link with each other to play up to 75 action, strategy and role-playing games, including Counter-Strike and EverQuest. That hasn't always been easy: An estimated 35,000 computer servers, for example, run Counter-Strike," reports USA Today.
"Enhancing Xfire's pedigree is its chief gaming officer, Dennis "Thresh" Fong, the world champion of action games Doom II, Quake and Quake II. He also founded the popular site Gamers.com."
