Because in ventrilo you are the admin, and can punish people who attempt to maliciously intrude, while xfire you can be spammed, while waiting for your complaint to be resolved.
Its like teamspeak, you host your own server where people can speak to eachother. As you own the server you can moderate everything very quickly, no waiting. Its always better to use something from yourself than a free service.
Is simple, is better than msn because it has exactly the same but this website including information, own a forum ,own clan ,contabilicacion of hours of gameplay that's enough, apart from that you can chat about chat rooms and create send and receive files over going it is a jewel ... thanks for your comment Pt3R people like Ace877 do not case.... :P
