GB: How do you intend to deal with massive amounts of "player-killing"? Will there be "safe" zones for those players that do not want to participate in Player-versus-Player games?

ArenaNet: Guild Wars is designed first and foremost as a competitive online role playing game. Nobody complains about player killing in StarCraft or chess, because those games are created to be competitive. Of course, as we’ve said before, Guild Wars will offer you the choice of competitive or cooperative games. You will make that choice simply by choosing the type of mission you want to play. Some quests or missions will be competitive, and in those, player-versus-player gaming and player-killing can be part of and maybe even the entire objective of the game. Those sorts of games would include the traditional PvP games, such as “Capture the Flag” or “King of the Hill.” Other quests or missions will be designated as strictly cooperative, and in those missions it will not be possible to kill other players.
