Yea, I don't have a 360 so I can't really comment on Xbox Live, but as far as the PSN goes I've played a few different games online, BF:BC, SOCOM, LBP, Warhawk, Resistance 2. From my experiences with that, first of all barring SOCOM people hardly use mics in the other games, most obviously because a mic doesn't come with the PS3. That is good and bad, bad because it prevents mic use from being widely accepted, but at the same time it is sort of good, because that means that people need to go out and get a mic so it cuts back on the abusive people factor. Mic use is particularly good in SOCOM though, and I've played SOCOM since the original and it's always been that way.
