Xfire is a game helper you can have open while your playing, the features include:
* Friend Tracker & Server Browser
* Instant Messaging While You Play
* File Download System
* Built-In Stats Tracking
* Play with People You Know
By built in stats tracking, I mean it records how many hours you've been playing on all games on your PC, all you have to do is download Xfire, register and account, and sign in before you play, it won't slow down your games or anything!
You get a profile page accessible by anyone that shows how many hours you've played on your games, total, and weekly, Xfire even allows you to embed it in a webpage!
I give this system two thumbs up!
Check it out,
