I've been playing some MMO's recently and always found chatting to my friends to be a hassle when you're busy killing stuff. I just had my first LAN type thing and found that just talking is so much easier and so much more fun that I've been considering getting a headset. Unfortunately the game itself doesn't have in-game voice chat so I'd need a program to run in the back ground for it. My question is, which should I get and why? It doesn't have to be Skype or Ventrilo, they are just the only ones I've heard of, but it does have to be free.
