i dont know if this is an urban legend but...
on ragnarok ph, a guild won a tourney and took home 1m php. (not sure) and the guild master killed...
the members so that he can get all the money for himself.
p.s. i dont know if this is real, i was googling it the whole night. So have you guys heard about it?
although there is a related violence with regards to a member and the GM and 1m peso in prize
