New Counter-Strike Matchmaking System Introduced - IGN News

Counter-Strike: Global Offensive (CS:GO) has received a new matchmaking system that analyses player behavior across Steam. According to the Counter-Strike blog, the new system has created something called a Trust Factor for Steam players. This system takes into account total time playing CS:GO, times players have been reported for cheating, and time spent playing other games on their Steam account, with all of these contributing to create a player's Trust Factor.
