Sigh, as much as I had hoped that you kept doing the voices by yourself (Quite frankly, Im here to listen to your commentary, not anyone elses (Well maybe for the podcasts)), looks like this is a permanent style. One thing I hope will happen is that you'll optimize the volumes of everyone to similar levels.
A bit of "professionalism" wouldnt hurt if youre willing to go that far, as in, and this would pretty much turn this from a Lets Play into an abridgion of sorts, recording everyones voices after playing the game.
