A few years ago I sold my 360 and went over to the PS3, while the Live community was buzzing!
Now, just recently I re-bought a 360 with all the exclusives (Halo, Gears, etc.) and a few other games with online play. I was shocked and, actually, really depressed to find not ONE single person using a mic these days..
I remember back in the GRAW, COD 2, Halo 3, Modern Warfare days, everyone had a mic and used it, the lobbies were full of chatter / flaming, and the games were just more fun to play when that was the case. I know that with Party Chat coming in, most people are either talking with friends or don't use the mic at all but I hate this.
Also, my friends list has about 50 or so people on it..there's only ever 1-3 MAXIMUM online at one time and the rest haven't been online since I re-bought the console...
It's depressingly dead. I wish it was like it used to be; lively, fun, a good way to make friends, or at the very least chat to some likeminded people. Alas I'm on Halo 4 right now and not one single mic connected..
Party Chat ruined my Live experience.
