U know I was amazed okay amazed, in how BAD!! the quality of the Xbox live chat system was when I bought my Xbox 360 2 years ago, because all I heard was Xbox live this Xbox live that, then I got it and noticed that the Voice chat quality was CRAP!! and no one to that point ever even mention it! even the video quality was crap too 90% of video "feeds" (not movies) on on live were not FULL screen lol..... Ya!! need less to say I have not paid for live and until I find a deal dirt cheap I'll probbably never will.
I have had my PS3 since day one and it has the best voice quality chat as good if not better then my cell and I'm sure it can handle cross game chat, why its not there? I though it was because microsoft had a pattent on it?? i don't know but I can't wait....
