I don't get what is so special about DotA. Player vs Player game exist even during the Windows 3.1 era but we never saw or heard anyone fighting over a game. I still remember playing Red Alert, Red Alert 2, Quake 2 and Unreal Tournament when I am around 14 years old in a CC but I never see anyone fight over getting pawned and insulted in the game. The loser will just admit defeat and leave without any "settle outside" remarks while the winner cheers.

Seriously, what is wrong to people these days.
