From my experiences with Shadowrun and Perfect Dark Zero, they seem to have a relatively low number of immature kids on them...

With Perfect Dark Zero, however, I've run across a good few people with British or English accents, ranting about how much they hate Americans. :/

...And one time, a kid was yelling at me for taking up a "sniping spot" in a map where the maximum firing distances was maybe 100 feet or so - when I was using a Falcon, against unarmored targets, and he decided a Jackal was necessary for that range (despite that, when he did get a spot, he couldn't hit anything with it). :/
