Just got a code for CB3. A question for those who've already played.
What in your opinion is the best voice chat program for this game? Skype, Vent, TS, or a different one? Or is there a system build into the game itself?

Mumble is good and cheap, my guild uses GSC which is free, but I kinda wish we had a mumble or vent server :P

Avoid Skype as much as humanly possible when playing video games, besides video sharing (Which still is an FPS hog). Skype causes many problems for some odd reason when you use their service while playing games. At least me and my guildies from numerous games have experienced.

Go with Teamspeak, Ventrilo, or any other equivilants that are very popular. They take up almost nothing and are configurable to the T past what Skype gives.

Mumble if you are looking to pay, very low latency and has a really nice UI for advanced and beginner users alike.

Raidcall if you are looking for something for free, can be a tad laggy but it will work.

I personally will not use anything other than mumble after raiding with it for the past 2 years. I look back on TS and think wow what a world of difference
