This is why the only online [competitive] shooter I play is Counter Strike Source. And even more specifically on the 007 server. Much more mature and laid back guys who even when giving shit, are obviously just joking and doing it in friendly banter. They're there for fun, not a dick measuring contest like the HALO, BF, or COD communities.
Particularly that the 007 server is full of people my age who grew up with the Goldeneye (N64) days of multiplayer and know better than those punk kids these days.
