hmm. hmmmhmmm
the first MMO ive played with - KnightOnline - had some similar place called Colony Zone
in that game there were two races, Orcs and Humans. CZ was the PVP zone of the game. partys were allowed and you could only fight the opposing race. if you/your party killed someone you got your share of the 50 National Points which a PK was worth. then there were top-lists based on these NPs, they were requied for guild level ups. was nice and great fun
oh, and the mobs there were also a little weaker but gave more xp, like described above
cant wait for it be opened, even tho id like partyplay more
